Why didn’t they make a normal pie chart?! That circle is not very good visualisation.
surface of the circle is directly proportional to the revenue, this presentation is much better to compare two values to each other (if you have problem comparing how much 367 is compared to 128 and need an image for that, that is). it would be harder in the pie chart.
if you want share of the total, the bottom graph is much better for that (and it adds layer of information that pie graph wouldn't have).
i assume that is why.
Circle area's are really hard to compare. A circle with double the area of another barely looks bigger.
But circles are hard to compare directly. A square would be much better or even a bar chart.
This is trying to be flashy and it gets in the way of the information.
Fair point. I do suppose it makes some sense, since otherwise the small ones would be barely visible slices, while they are more concentrated here.
Maybe because the two top mediums shown are circular shaped, a CD and a vinyl record.
Probably because they wanted to show the variance over time which one pie chart cannot visually show. And it's easier to compare a circle vs a circle than a pie chart.
