There are some ready-to-enjoy exemplary Plato reports, such as the one for jQuery. The summary page, as shown below, is useful to give a quick comparison of the different source files, in terms of code complexity, lines of code (LOC), etc.
Clicking on one of the bars will open a detailed report. Particularly interesting here is the complexity distribution (depicted in a fancy donut chart) of various functions in that particular source file. Even better, when you choose a segment and click on it, it will jump to the source code directly.
While the code view is beautiful (with syntax highlighting and such), an interesting feature here is the analysis overlay. If a function is marked with dotted border, you can hover there and there will be a nice analysis tip.
Who says code analysis can’t be fun?
