The following chart traces the flow of funds into AI (artificial intelligence) startups.
I found it on this webpage and it is attributed to Financial Times.
Here, I apply the self-sufficiency test to show that the semicircles are playing no role in the visualization. When the numbers are removed, readers cannot understand the data at all. So the visual elements are toothless.
Actually, it's worse. The data got encoded in the diameters of the semicircles, but not the areas. Thus, anyone courageously computing the ratios of the areas finds their effort frustrated.
Here is a different view that preserves the layout:
The two data series in the original chart show the current round of funding and the total funds raised. In the junkcharts version, I decided to compare the new funds versus the previously-raised funds so that the total area represents the total funds raised.
