dsh-artifact

Turn natural-language requests into native, interactive ECharts and Mermaid visualizations inside DeepSeek Harness.

简体中文

What it is

dsh-artifact is a visualization renderer for DeepSeek Harness. Ask for a chart or diagram in ordinary language; the model understands the intent, chooses the appropriate native engine, emits a declarative payload, and the result appears directly in the conversation as an interactive canvas.

It is built for a near-native ECharts and Mermaid authoring experience—not a small set of hand-drawn chart templates. The browser receives a real ECharts option or Mermaid source and renders it with the real engine.

Your request  →  model understands the intent  →  ECharts option / Mermaid code  →  interactive canvas

Highlights

From a request to a native canvas

Describe the visualization you need in ordinary language. dsh-artifact keeps the complete workflow inside the conversation: the model reasons about the request, prepares a native engine payload, and renders the result as an interactive canvas with appearance controls and PNG export.

_{One request, from streamed reasoning and tool execution to a native ECharts calendar heatmap. The demonstration preserves the actual DeepSeek Harness interface.}

Built around real rendering engines

Install

Install the DeepSeek Harness CLI first (one time):

npm install -g @deepseek-ai/dsh

If this is your first time using DSH, run dsh web once to initialize the web profile, then stop it before adding the plugin.

# GitHub install (recommended; prebuilt engine assets are included)
dsh plugin --profile web add github:sumarilkkxx/dsh-artifact

# Local development
dsh plugin --profile web add link:/path/to/dsh-artifact

Start or restart dsh web, then hard-refresh the browser (Cmd/Ctrl+Shift+R). pnpm must be available on PATH because the DSH plugin command uses it internally.

Use it naturally

Ask for the result you need. For example:

Compare quarterly revenue and margin for 2024 in a dual-axis chart, highlight the best quarter, and use a dark canvas.

Create a GitHub-style calendar heatmap for this year's daily commits.

Draw a sequence diagram for OAuth login with success and failure paths.

The model calls render_artifact and returns a live canvas in the conversation. Use the Appearance control to switch palette/background where appropriate, and the adjacent Download action to save a PNG.
