These visualizations look great! But I don��t know what they mean. When one hovers the mouse over the visualizations, does help text appear explaining what one is looking at? For example, I guess that the red and green segments in ��Lines of Code�� refer to lines deleted and added. But what are the green and yellow for ��Classes��. And what��s a ��Function�� in Pharo?

The more complicated diagram for ��Roassal2�� I can��t even begin to guess at! Don��t make the mistake of thinking that because you know what the diagram means, after working on it for months, that other programmers will also know.
