plotly

plotly is a skill for Claude Code, Codex from tondevrel/scientific-agent-skills. It costs 93 tokens per session (2,849 once invoked), scanned A, original, MIT.

A Python library for making interactive charts and dashboards. Its charts can run in a browser and let viewers zoom, pan, hover over data, and explore three-dimensional or geographic data.

In plain words
What is it for?
Use it for interactive charts in web apps and notebooks, 3D plots, maps, financial charts, animated time series, and dashboards built with Dash.
Why use it?
It avoids building these interactions by hand when a static chart is not enough. It supports both quick chart creation from tables and detailed control over individual chart elements.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

plotly scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Plotly - Interactive Visualization

Plotly provides a wide range of interactive charts. Its "Plotly Express" API is designed for speed and ease of use with tidy DataFrames, while "Graph Objects" offers low-level control over every trace and attribute.

When to Use

  • Creating interactive charts for web applications or Jupyter notebooks
  • Visualizing 3D data (surfaces, scatter, mesh)
  • Geographic maps (scatter on maps, choropleths) with Mapbox integration
  • Financial charts (candlestick, OHLC)
  • Exploring large datasets where zooming into specific regions is required
  • Creating animations (time-series sliders)
  • Building production-ready dashboards (via Dash)

Reference Documentation

Official docs: https://plotly.com/python/
Plotly Express: https://plotly.com/python/plotly-express/
Search patterns: px.scatter, go.Figure, fig.update_layout, fig.write_html, px.choropleth

Core Principles

Plotly Express (px) vs. Graph Objects (go)

Feature Plotly Express (px) Graph Objects (go)
Complexity High-level, concise. Low-level, verbose.
Data Format Tidy (long-form) DataFrames. Lists, Arrays, Dicts, or DataFrames.
Customization Good (using update_*). Maximum / Full control.
Speed of Dev Very fast. Slower.

Use Plotly For

  • Interactive exploration (hover, zoom)
  • 3D and Geospatial visualization
  • Exporting to standalone interactive HTML files
  • Integration with Dash

Do NOT Use For

  • Publication-quality static LaTeX plots (use Matplotlib)
  • Very large static image generation (Matplotlib is faster)
  • Low-memory environments (Plotly's JSON-based figures are memory-heavy)

Quick Reference

Installation

pip install plotly pandas

Standard Imports

import plotly.express as px
import plotly.graph_objects as go
import pandas as pd
import numpy as np

Basic Pattern - Plotly Express

import plotly.express as px

# Load data
df = px.data.iris()

# Create interactive scatter plot
fig = px.scatter(df, x="sepal_width", y="sepal_length", 
                 color="species", size="petal_length",
                 hover_data=['petal_width'])

# Display
fig.show()

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

plotly is a skill published in the GitHub repository tondevrel/scientific-agent-skills (19 stars, last pushed 7mo ago), licensed MIT. It adds 93 tokens to every session and 2,849 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
