## What it does

Hand it a dataset and the skill decides what it is looking at: a time series, a category comparison, parts of a whole, or relationships between points. It then reads the matching spec in `references/` and maps your numbers onto the `args` fields. Rendering runs through `node ./scripts/generate.js '<payload_json>'`, where the payload is JSON with a `tool` field and an `args` object.

There are 26 tools behind it. `generate_line_chart` and `generate_area_chart` cover trends, `generate_bar_chart` and `generate_column_chart` handle comparisons, `generate_pie_chart` and `generate_treemap_chart` split parts of a whole. Maps come as `generate_district_map`, `generate_pin_map` and `generate_path_map`. The rest range from `generate_radar_chart`, `generate_funnel_chart` and `generate_word_cloud_chart` to `generate_boxplot_chart` and `generate_violin_chart`. `generate_spreadsheet` is the odd one out — tabular and pivot output rather than a picture.

Node.js 18.0.0 or newer is required, otherwise the script will not start. Results go to stdout: an image URL for chart types, text or JSON for map tools. Failures land on stderr, and the process exits with status 1 if any item in a batch fails, though it still prints URLs for the ones that worked. So only show a URL when the command exits 0.

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/bytedance/deer-flow/tree/HEAD/skills/public/chart-visualization/SKILL.md

## When to use it
- pick a chart type that fits the shape of the data
- fill generation arguments from the spec
- render a chart image without hand-coding layout
- map regions, points or routes
- turn a dataset into a pivot table

## Example prompts
- Chart this year of sales as a line graph
- Compare these categories with a bar chart
- Map these cities as a district map

# Chart Visualization Skill

This skill provides a comprehensive workflow for transforming data into visual charts. It handles chart selection, parameter extraction, and image generation.

## Workflow

To visualize data, follow these steps:

### 1. Intelligent Chart Selection
Analyze the user's data features to determine the most appropriate chart type. Use the following guidelines (and consult `references/` for detailed specs):

- **Time Series**: Use `generate_line_chart` (trends) or `generate_area_chart` (accumulated trends). Use `generate_dual_axes_chart` for two different scales.
- **Comparisons**: Use `generate_bar_chart` (categorical) or `generate_column_chart`. Use `generate_histogram_chart` for frequency distributions.
- **Part-to-Whole**: Use `generate_pie_chart` or `generate_treemap_chart` (hierarchical).
- **Relationships & Flow**: Use `generate_scatter_chart` (correlation), `generate_sankey_chart` (flow), or `generate_venn_chart` (overlap).
- **Maps**: Use `generate_district_map` (regions), `generate_pin_map` (points), or `generate_path_map` (routes).
- **Hierarchies & Trees**: Use `generate_organization_chart` or `generate_mind_map`.
- **Specialized**:
    - `generate_radar_chart`: Multi-dimensional comparison.
    - `generate_funnel_chart`: Process stages.
    - `generate_liquid_chart`: Percentage/Progress.
    - `generate_word_cloud_chart`: Text frequency.
    - `generate_boxplot_chart` or `generate_violin_chart`: Statistical distribution.
    - `generate_network_graph`: Complex node-edge relationships.
    - `generate_fishbone_diagram`: Cause-effect analysis.
    - `generate_flow_diagram`: Process flow.
    - `generate_spreadsheet`: Tabular data or pivot tables for structured data display and cross-tabulation.

### 2. Parameter Extraction
Once a chart type is selected, read the corresponding file in the `references/` directory (e.g., `references/generate_line_chart.md`) to identify the required and optional fields.
Extract the data from the user's input and map it to the expected `args` format.

### 3. Chart Generation
Invoke the `scripts/generate.js` script with a JSON payload.

**Payload Format:**
```json
{
````
