Visualizing the meaning of log-scales

Plotting in log-scale is often the only way of displaying a given dataset. Unfortunately, log-scales are more difficult to understand even for trained eyes. Often, it is used the formula "note the log-scale of y-axis" in the figure legend. However, it hardly makes the plot easier to follow for log-adverse people. This plot shows an elegant way to display the untransformed data and, at the same time, benefiting from the illustrative power of a log-scale.
