• Customizable tooltip.
• Instant zoom span on click (no animation).

Graph Types

• ChildrenCallCount: Count all children recursively for a span and gives the space according to the count. Useful if you want all entries to show up.
• Timestamp: Uses the fields "entryTime" and "exitTime" to place the spans. It will not show entries with interval of 0. Used for performance flamegraph.
