Data Vis Dispatch, April 15: Stocks, public opinion, and the #30DayChartChallenge
Welcome back to the 189th edition of Data Vis Dispatch! Every week, we’ll be publishing a collection of the best small and large data visualizations we find, especially from news organizations — to celebrate data journalism, data visualization, simple charts, elaborate maps, and their creators.
The Data Vis Dispatch will take a break next week for Easter, and return for a longer edition the week after.
Recurring topics this week include the stock market, public opinion polling, and the 30 Day Chart Challenge.
With another week of Trump's economic ideas behind us, here are new charts trying to get behind it all:



The first place to look for the consequences of tariffs is the stock market, which went crazy (but not as crazy as it has in the past), and even seemed to show signs of insider trading:

Here are a few graphics about the environment, energy trends, and climate misinformation:

Taking a look at the world of politics, we found charts on government structure and effectiveness, as well as some nice classic poll trackers:

The #30DayChartChallenge continues, bringing us more self-published visualizations — distributions seemed to be a common theme in the past few days:
