What plotly does

This skill equips Claude Code with structured workflows for Python data visualization. The assistant learns when to rely on concise plotly.express methods for tabular pandas data and when to switch to granular graph_objects for custom figure layouts, 3D meshes, and complex annotations.

The reference material covers over 40 chart variations, including candlesticks, heatmaps, density maps, and violin plots. It also guides the agent through grid subplots with make_subplots, styling themes, hover templates, and time sliders.

Static image generation for PNG, PDF, or SVG formats requires the kaleido package. Without that dependency installed, Plotly will only output standalone HTML files.

What it helps with

  • generate interactive statistical plots from pandas DataFrames
  • build financial candlestick figures with time-range sliders
  • assemble multi-panel dashboards using make_subplots
  • export interactive visualizations into standalone HTML files

Example prompts for the agent

  • Create a correlation heatmap from this dataset using plotly.express
  • Build a candlestick chart with a date rangeslider and save it as HTML
  • Set up a 2x2 dashboard using graph_objects subplots with a dark theme
