42.1 Chart Choice

Chart Choice is a UI/UX design skill that helps make products easier to understand, use, test, and improve. The method should be tied to a real user problem instead of decoration alone.

Step by step

  1. Define the user problem connected to Chart Choice.
  2. Collect evidence before jumping to a polished solution.
  3. Create the smallest flow, sketch, wireframe, prototype, or test needed to answer the question.
  4. Test the design with realistic content, states, and device constraints.
  5. Record what you learned and change the design based on evidence rather than preference.

10 practical examples

  1. Apply Chart Choice to a course website and explain the decision you made.
  2. Apply Chart Choice to a online store and explain the decision you made.
  3. Apply Chart Choice to a banking app and explain the decision you made.
  4. Apply Chart Choice to a school portal and explain the decision you made.

Hands-on example

UI/UX PRACTICE
Problem: A user struggles with Chart Choice.
Evidence to collect: interview, observation, analytics, or usability result.
Artifact: flow, sketch, wireframe, prototype, or test plan.
Success measure: task completion, clarity, error reduction, or satisfaction.
Next step: test one assumption.

Expected output

A user-centered design artifact for Chart Choice plus a clear statement of what evidence would confirm or reject the design decision.
