# Tufte: Information Design The central tenet: **"Above all else, show the data."** — VDQI, p. 92 Every design decision flows from this. If a mark, color, grid line, or label helps the viewer understand the data, it earns its place. If it doesn't, it should be erased. --- ## Two Entry Workflows Read the user's intent and enter the right workflow: - **Design from scratch** — user has data and wants to make a graphic - **Critique existing** — user has a graphic and wants it improved Both workflows end at the same ship checklist in `references/checklists.md`. --- ## Workflow A: Design from Scratch ### Step 1 — Clarify the question Before selecting any form, ask: - **"Compared to what?"** Every graphic implies a comparison. Make it explicit. What baseline, alternative, or change over time matters? - What is the single most important thing the viewer should see? - Who is the audience, and what can they take action on? - How many variables are in the data, and how many dimensions of variation matter? If the user can't answer "compared to what?" in one sentence, the data question isn't formed yet. Clarify before designing. ### Step 2 — Choose the form Use this decision tree to pick the right chart type. When in doubt, default to the simpler, more honest form. | Goal | Recommended form | Avoid | | --------------------------------------------- | -------------------------------
