For the purposes of this article, this graph is much more effective at making the point than the log scale one. I think it would have been a better choice to use a graph like this.
Thank you! That graph is so much clearer than the one in the article. You can see at a glance the relative size of the two programs, which the logarithmic scale does a terrible job showing.
I'm a technical audience and the logarithmic scale is meaningless to me. So I don't even agree that it's a good choice for a technical audience. It may be a good choice for people who already are used to reading logarithmic scales, but that can't be a particularly large group as it's very rare to see a graph like that.
