Works for that chart. But its depends on the author to draw the components that way, next to each other, and orient the chart so its obvious. And still, what other combinations add up to half? Can&#x27;t tell from that chart. One with values side-by-side and a scale would allow you to do the math.<p>Pie charts are not serious graphs. They are useful for arguing points, where you (deliberately?) don&#x27;t want to confuse folks with numbers.
