1. Select an example on the input tab, e.g. "CTESimple"
2. Go back to the input tab.
3. Click into the JSON textarea on the left, then hit Cmd+A to select all text inside of it (see Fig 1)
4. Optional: Paste some new JSON (could be the same, just Cmd+C and Cmd+V)
5. Notice how the text selection bleeds into the FlameGraph tab : ( (see Fig 2)
