Add an inline line or bar chart to an xopc chat response when comparing numerical trends or categories helps the user understand data.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Chat Charts Use a chart when it adds understanding to a numerical comparison. Prefer a table for a few isolated values. This skill produces chat content; it does not fetch data or create a separate application. Before emitting a chart, read [references/chart-spec.md](references/chart-spec.md) for the exact v1 protocol and examples. With xopc, load it using `skill_view(name="chat-charts", path="references/chart-spec.md")`. Output a strict JSON object in a fenced block tagged `chart`, with ordinary explanatory Markdown around it. The xopc Web chat renderer validates it and converts it to a themed interactive chart. Other clients may display the source; include a concise textual conclusion outside the block. Choose `line` for an ordered trend and `bar` for category comparisons. Preserve the source's order, numbers, units and precision. All series share one unit and axis; split different units into separate charts. Use only obtained data; do not fill gaps with invented values. Missing measurements are `null`, never an assumed zero. …

How to install
mdr add xopcai/xopc/chat-charts@sha256:6e4f1cd269074e3dThe line at the top of this page pins the label git:20261017.91622d3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
