visualization-selection

A guide for choosing a chart or plot based on the relationship the data needs to show. It covers comparisons, distributions, trends, correlations, and parts of a whole.

In plain words
What is it for?
Selecting charts for reports and dashboards, then applying basic rules for labels, units, colors, and honest axes.
Why use it?
It helps prevent using a chart type that hides or distorts the pattern in the data.

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

visualization-selection 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 3d 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.

What it actually says

Visualization Selection Guide

Goal Chart Type
Compare categories Bar chart (horizontal if many labels)
Show distribution Histogram, box plot, violin plot
Show trend over time Line chart
Show correlation Scatter plot, heatmap
Show part-to-whole Pie (<=5 slices), stacked bar

Principles:

  • Label axes and include units.
  • Use color purposefully — not just for decoration.
  • Avoid 3D charts; they distort perception.
  • Start y-axis at 0 for bar charts (truncated bars mislead).
  • Use a colorblind-safe palette (e.g., viridis, colorbrewer).

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.
