I appreciate the work that went into making this post.
However where the author failed was in colour choice, specifically on the charts. Subdued hues are fine as a statement for a theme, not when you're trying to discern which subdued hue of blue matches which Python Web server.
I don't know if you're already aware of this, but you can hover/click labels to make lines on the graph highlight and disappear respectively. I've found that these features make the graphs much easier to read.
That said, I definitely agree there needs to be an improvement to the colours used.
Indeed, the lines are pretty hard to distinguish. The graphs are interactive though, as you can hover over the legend, or over the graph, and the current line is highlighted.

More distinct colours please!
