Summary Flame Graph / Flame Chart toggle

This is a follow on from Bug 111162 "Web Inspector: implement Flame Chart for CPU profiler". Flame charts are awesome. This feature request is for a toggle button to switch between flame charts and flame graphs. Both of these visualize the same profile data, with the only difference the x-axis: - Flame Charts: x-axis shows the passage of time. Time-based patterns can be identified. For long profiles with short and changing code paths, the stack "flames" can appear thin and hard to read. - Flame Graphs: x-axis sorts the stacks alphabetically, from origin to leaf. This maximizes merging of frames, allowing the big picture of CPU usage to be visualized. These can be useful in other cases, for example, non-regression testing, where a pair of flame graphs can be visually compared and small differences seen. An explanation for flame graphs is: http://www.slideshare.net/brendangregg/blazing-performance-with-flame-graphs/35. It would be awesome to have a tool that can toggle between both types of visualization for the same profile data.
