## Description

This skill should be used when the user wants to visualize data. It intelligently selects the most suitable chart type from 26 available options, extracts parameters based on detailed specifications, and generates a chart image using a JavaScript script.

# 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.
