dsh-echarts

When a model replies with data in a DSH conversation, the chart often stays as a wall of JSON inside a code fence, and you still have to copy it into a browser and run it yourself. dsh-echarts removes that extra step: as soon as the model emits an echarts-fenced Strict JSON block, the plugin automatically renders it into a fully interactive Apache ECharts Canvas chart right in the Web UI, with zero additional tool calls and no manual run action required.

The result is not a static snapshot. Every native ECharts interaction is preserved, including tooltip hover, legend filtering, data-region zooming, and image export, and the chart adapts automatically to the DSH light or dark theme as well as container resize events. On the performance side, ECharts is lazy-loaded: the library initialises only when a chart scrolls close to the viewport, and multiple charts render serially so long conversations stay lightweight. The ECharts bundle ships locally with the plugin with no CDN dependency, JSON input is treated as untrusted and validated, and if rendering fails the original source is kept intact alongside a copyable error message.

It is built for any workflow where you want to see the chart instead of the code: data-analysis conclusions, operations dashboards, experiment comparisons, trend narratives, or simply a dual-axis bar-and-line chart, a donut breakdown, a radar, or a Sankey diagram that should appear as a living visual rather than a JSON blob. As long as the chart option can be expressed in pure JSON, ask the model in one sentence and the chart appears in the next.
