Version 1.2.0.post1 fixes a problem in the setup of version 1.2.0, which ignored all requirements. There are no further changes to the software.

Version 1.2.0 brings improvement to the code drawing the ember graphs without changing how the input data is converted to colours in the graphs; it improves to the layout of the diagrams; it provides a new, clearer web user interface, and describes the examples in a much better way.
