| 3 | * last two weeks, day by day. Above the line, pull requests opened and |
| 4 | * merged and commits agents pushed outside one (bars), and agent sessions |
| 5 | * started (a wash); below it, reviews and |
| 6 | * comments (a wash) and requests for changes (bars). Each row is drawn to |
| 7 | * its own scale, so a small team's week is as legible as a big one's; the |
| 8 | * numbers are in the readout and the table. Layers turn on and off above |
| 9 | * the rows, and pointing at a day says what happened on it. |
