Unifies market analysis, data analysis, and consulting reporting into a comprehensive consulting-analysis skill, enabling a two-phase workflow from analysis framework design to professional report generation. Introduces a DuckDB-based data analysis utility for Excel/CSV files and a chart-visualization skill with a flexible JS interface and extensive chart type documentation. Removes the legacy market analysis skill to streamline report generation and improve extensibility for consulting and data-driven workflows.

# 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
|
|
{
|
|
"tool": "generate_chart_type_name",
|
|
"args": {
|
|
"data": [...],
|
|
"title": "...",
|
|
"theme": "...",
|
|
"style": { ... }
|
|
}
|
|
}
|
|
```
|
|
|
|
**Execution Command:**
|
|
```bash
|
|
node ./scripts/generate.js '<payload_json>'
|
|
```
|
|
|
|
### 4. Result Return
|
|
The script will output the URL of the generated chart image.
|
|
Return the following to the user:
|
|
- The image URL.
|
|
- The complete `args` (specification) used for generation.
|
|
|
|
## Reference Material
|
|
Detailed specifications for each chart type are located in the `references/` directory. Consult these files to ensure the `args` passed to the script match the expected schema. |
