Four tips for making a good infographic

Posted on by

The head of a new infographic website suggests four tips for making a good infographic:

1. Apply a journalist’s code of ethics

An infographic starts with a great data set. Even if you’re not a journalist — but an advertiser or independent contractor, say — you need to represent the data ethically in order to preserve your credibility with your audience. Don’t source from blogs. Don’t source from Wikipedia. Don’t misrepresent your data with images.

2. Find the story in the data

There’s a popular misconception that creating a great infographic just requires hiring a great graphic designer. But even the best designer can only do so much with poor material. Mapping out the key points in your narrative should be the first order of business. “The most accessible graphics we’ve ever done are the ones that tell a story. It should have an arc, a climax and a conclusion,” Langille says. When you find a great data set, mock up your visualization first and figure out what you want to say, before contacting a designer.

3. Make it mobile and personal

As the media becomes more sophisticated, designers are developing non-static infographics. An interactive infographic might seem pretty “sexy,” Langille says, but it’s much less shareable. A video infographic, on the other hand, is both interactive and easy to port from site to site. Another way to involve readers is to create a graphic that allows them to input and share their own information.

4. Don’t let the code out

One of the easiest ways to protect your work is to share it on a community site. Visual.ly offers Creative Commons licensing to users who upload a graphic to the site. When visitors who want to use the graphic grab embed code from the site, the embedded image automatically links back to its creator. Langille suggests adding branding to the bottom of your work and never releasing the actual source file — only the PNG, JPEG, or PDF. And what if your work goes viral without proper credit? For god’s sake, don’t be a pain and demand that the thieves take it down. “It’s better to let it go and ask for a link back and credits on the graphics,” Langille said.

The first two points apply to all charts and graphs: you need to have good and compelling data and then use the graphic to tell this story. Infographics should make the relevant data easier to understand than having someone read through denser text. An easy temptation is to try new ways of displaying data without thinking through whether they are easily readable.

It would be interesting to know whether infographics are actually more effective in conveying information to viewers. In other words, is a traditional bar graph made in Excel really worse in the basic task of sharing information than a snazzy infographic? I imagine websites and publications would rather have infographics because they look better and take advantage of newer tools but a better visual does not necessarily equal connecting more with viewers.

Side note: the “meta Infographic” at the beginning of this article and the “Most Popular Infographics You Can Find Around the Web” at the end are amusing.

Data guru Hans Rosling named to Time’s 100 most influential people

Posted on by

Hans Rosling’s talks are fascinating as he makes data and charts exciting and explanatory in his own enthusiastic manner. Named as one of the 100 most influential people by Time, Rosling is profiled by sociologist and MD Nicholas Christakis:

Hans Rosling trained in statistics and medicine and spent years on the front lines of public health in Africa. Yet his greatest impact has come from his stunning renderings of the numbers that characterize the human condition.

His 2006 TED talk, in which he animated statistics to tell the story of socio-economic development, has been viewed over 3.8 million times and translated into dozens of languages. His subsequent talks have moved millions of people worldwide to see themselves and our planet in new ways by showing how our actions affect our health and wealth and one another across space and time.

When you meet Rosling, 63, you are struck by his energy and clarity. He has the quiet assurance of a sword swallower (which he is) but also of a man who is in the vanguard of a critically important activity: advancing the public understanding of science.

What does Rosling make of his statistical analysis of worldwide trends? “I am not an optimist,” he says. “I’m a very serious possibilist. It’s a new category where we take emotion apart and we just work analytically with the world.” We can all, Rosling thinks, become healthy and wealthy. What a promising thought, so eloquently rendered with data.

Here are some of Rosling’s presentations that are well worth watching:

–200 Countries, 200 Years, 4 minutes – The Joy of Stats

–TED Talk: No More Boring Data

–TED Talk: The Good News of the Decade?

Here is what The Economist thinks are Rosling’s greatest hits.

I’ve used several of Rosling’s talk in class to illustrate what is possible with data and charts. Rosling gets at an important issue: data should tell a story and be interactive and available to people so they too can dig into it and understand the world better. By simply taking a chart and adding some extra information (like population size of a country displayed as a larger circle or being able to quickly show the quartile income distributions for a country) and the dimension of time, you can start to visualize patterns and possible explanations of how the world works.

(A side note: alas, I don’t think any sociologists were named as one of the 100 most influential people.)

Making sure the graph of mean age of marriage covers a broad enough period of history

Posted on by

Two days ago, I noted a new report that said that fewer adult Americans, 51%,  are married than ever before. One of the markers of this trend is the rising mean age for a first marriage. But, a sociologist points out that it is important to have a broad enough context for the mean age of marriage:

But Philip N. Cohen, a sociologist at the University of North Carolina at Chapel Hill, reminds us that using 1960 as a reference point can be misleading.

In 1960, the median age of first marriage was near a record low, having bottomed in about 1956. If you check out the trends going back to 1890, however, you get a much different picture…

“[T]he 1950s,” Professor Cohen writes, “doesn’t represent the ‘traditional’ family.”

The graph is pretty clear: the 1950s represent a clear dip in the mean age of marriage between 1890 and today. Suggesting there is a sharp rise since the 1960s in the mean age is not incorrect but it masks the bigger context.

This leads me to an interesting idea: while the 1960s are often considered an unusual decade and perhaps one whose reverberations are still being felt (consequences of foreign wars, sexual revolution, rise of youth culture, Baby Boomers, challenges to political authority, etc.), perhaps it is the 1950s that is the real unusual decade in the United States. The swift movement of people to the suburbs, a large crop of war veterans going back to school and starting families, an expanding economy, and relative peace (with the US as a clear superpower) represents an unusual period. Perhaps then the 1960s were simply the beginning of the unraveling of that “golden decade.”

The social history of the food pyramid

Posted on by

With the unveiling later this week of a replacement to the food pyramid (it will be a “plate-shaped symbol, sliced into wedges for the basic food groups and half-filled with fruits and vegetables”), the New York Times provides a quick look at the background of the food pyramid:

The food pyramid has a long and tangled history. Its original version showed a hierarchy of foods, with those that made up the largest portions of a recommended diet, like grains, fruit and vegetables, closest to the wide base. Foods that were to be eaten in smaller quantities, like dairy and meat, were closer to the pyramid’s tapering top.

But the pyramid’s original release was held back over complaints from the meat and dairy industry that their products were being stigmatized. It was released with minor changes in 1992.

A revised pyramid was released in 2005. Called MyPyramid, it turned the old hierarchy on its side, with vertical brightly colored strips standing in for the different food groups. It also showed a stick figure running up the side to emphasize the need for exercise.

But the new pyramid was widely viewed as hard to understand. The Obama administration began talking about getting rid of it as early as last summer. At that time, a group of public health experts, nutritionists, food industry representatives and design professionals were invited to a meeting in Washington where they were asked to discuss possible alternative symbols. One option was a plate.

Two things stand out to me:

1. This is partly about changing nutritional standards but also is about politics and lobbying. Food groups are backed by businesses and industries that have a stake in this. Did they play any part in this new logo?

2. This is a graphical design issue. The old food pyramid suggests that certain foods should be the basis/foundation for eating. The most recent pyramid is a bit strange as the pyramid is broken into slivers so the peaking aspect of a pyramid seems to have been discarded. The new logo sounds like it will be a more proportional based object where people can quickly see what percentage of their diet should be devoted to different foods. Since this is a logo that is likely to be slapped on many educational materials and food packages, it would be helpful if it is easy to understand.

Chart of total carbon emissions and emissions per capita

Posted on by

Miller-McCune has put together two charts showing total carbon emissions by country and also emissions per capita by country. See the two charts here.

This is colorful and vibrant. And it is nice to have the charts side-by-side as one can easily make comparisons. For example, the US is #2 in total emissions but #9 in per capita emissions. As The Infrastructurist points out, the chart gives some insights into how many countries might need to deal with per capita emissions rather than point fingers at countries with the largest amount of carbon emissions.

But there is a lot of information compressed in this chart – it is hard to see a lot of the smaller countries with small circles. Additionally, why are the countries in the order they are? It appears that regions are together but the order is not the same for both charts and it certainly isn’t rank-ordered (China and US are on opposite ends of the chart for total emissions). The color and vibrancy seems to be more important to the chart-makers than having a logical order to the countries.
