Usage telemetry chart
Render a seven-day, multi-colour stacked SVG chart from the configured Graphite render endpoint:
bun ./usage-telemetry-chart.ts --render-url http://graphite:8080 --prefix piclaw
--prefix is the Graphite root before the instance segment and defaults to piclaw. Optional filters: --instance, --provider, --model, --metric tokens.total, and --days 7.
The chart reads instance-first paths such as piclaw.smith.usage.github-copilot.gpt_5_6_sol.tokens.total. It does not query the pre-0.1.14 piclaw.usage.<instance>... namespace.
The exporter add-on must be configured and have sent metrics before this chart has data.
