In this example, we use an article that comes from The New York Times. The New York Times is particularly famous for using very clever and very well-designed data visualizations in their articles to explain visually the concepts that are described verbally in the article. In this specific case, I've selected an article whose title is "How Americans Think About Climate Change, in Six Maps". This is by Nadja Popovich. John Schwartz, and Tatiana Schlossberg. And it's been published on March 21st, 2017. So, let's see. So the idea here is to show data, to talk about data that has been released by the Yale Program on Climate Communication and that gives a detailed view of public opinion on global warming. The first chart that they show is a map. And in this map, what is shown is the percentage of adults per congressional district who support strict CO2 limits on existing coal-fired power plants. And as you can see, there is quite a lot of support and this support tend to be higher on the west coast and there is also some concentration up here in the east coast, New York State and in its neighborhood. Okay, so then, the journalist describes some of these findings and go to the next finding. The next one is, most people think that climate change will harm Americans but they don't think it will happen to them. And there is another visual representation. Again, two maps showing the percentage of adults per country who think, on the left, global warming will harm people in the United States, or global warming, on the right, will harm me personally. And what is really interesting is that you can see a big difference between these two maps. There are way, way fewer people that think that global warming will harm them personally. But the same people think that global warming is going to harm someone in the United States, let's say, globally. So that's a very interesting comparison. And as you can se, the two visualizations here are communicating this information very, very directly. The next one I want to show you is the one about Texas and Florida. So here, the authors focus on two specific states. Texas and Florida are vulnerable to climate change but residents are split on how much to worry about it. And again, we have percentage of adults per county who are at least somewhat worried about global warming. And here, you can see how these information is distributed in Florida. And as you can see, the percentage is way, way higher in the area around Miami and Keys. And we have a similar trend in Texas. The closer we are to the coast, the more worried people are. So once again, this is an example of explanatory visualization. These interesting and beautiful charts and maps are used in an article to explain these complex concepts that are extracted from data.
