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.
