Flame graph colors

Original flame graphs use random colors to help visually differentiate adjacent frames. Variations include inverting the y-axis (an "icicle graph"), changing the hue to indicate code type, and using a color spectrum to convey an additional dimension. Flame graphs are both a static and dynamic visualization.

The x-axis represents the recording, over time. Each bar represents an event. A wider bar means that event took longer. The y-axis represents the call stack. When events are stacked on top of each other, it means the upper events caused the lower events.
