Creates charts and visual summaries from tabular or numeric data. Use for: visualize data, chart this, plot results, graph this.
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
# Data Visualizer ## When to Use - User says **visualize data** or task matches this capability - User says **chart this** or task matches this capability - User says **plot results** or task matches this capability - User says **graph this** or task matches this capability ## Workflow 1. Parse data source (CSV, JSON, spreadsheet). 2. Choose chart type: bar, line, pie, scatter (default bar for categories). 3. Generate visualization code or image. 4. Include title, labels, and one-sentence insight. ## Integrations - `xlsx` - `insight-synthesizer` ## Error Handling | Failure | Response | |---------|----------| | Malformed data | Show first 5 rows; ask user to fix format. | ## Gotchas - Prefer code-generated charts over hand-drawn ASCII for accuracy. ## Example **Input:** User request matching triggers above. **Output:** Structured result per workflow with integrations invoked as needed.

How to install
mdr add stijnman/grok-custom-skills/data-visualizer@sha256:8d593f2927a6e197The line at the top of this page pins the label v1.2.0, 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.
