dsh-viz

Visualization plugin for DeepSeek Harness: gives the model a chart_render tool that turns structured data into a self-contained ECharts HTML artifact inside the active workspace. Host-only — no client bundle; the artifact opens in any browser or file preview.

Status: example / reference skeleton from awesome-deepseek-harness. Structure follows observed community plugin conventions (see plugins/README.md); not yet verified against a live DSH instance.

Install

pnpm install && pnpm build
dsh plugin --profile  add file:/absolute/path/to/plugins/dsh-viz

Then restart that profile.

Tool: chart_render

Parameter	Type	Notes
title	string	chart title, also drives the default file name
chart_type	string	line | bar | pie | scatter
categories	json	x-axis labels for line/bar
series	json	[{ name?, data }]; pie data items are { name, value }, scatter items are [x, y]
filename	string	optional, relative to the chart directory; workspace-confined

Returns { path, chartType, seriesCount }. Writes are confined to the active workspace root (path-traversal is rejected).
