I really wish people would use log scale for this kind of graph.<p>Trying to study rates of growth on a linear scale is basically impossible during exponential-ish growth periods. All but the rightmost end of the chart gets squished flat along the horizontal axis.<p>Similarly, charts of e.g. currency exchange rates, stock indices, comparative economic growth between countries, etc. should most of the time be plotted with a log-scaled vertical axis. Otherwise there’s no way to accurately compare slopes in different parts of the chart, which can be deeply misleading.
