What this is
Learn to choose the right chart for the question, strip out clutter, use color and labels deliberately and assemble a simple one-page dashboard. Works with the spreadsheet or BI tool you already use. The course is organized into 6 modules — seeing the question, chart choice, decluttering, color and emphasis, honest visuals and dashboards and reports — with 18 lessons in total, so you build the skill in a sensible order and can return to any part when you need it.
It does not cover advanced statistics or teach any one BI tool in depth, and it will not make weak data say something it does not. The focus is on clear, honest charts you can build in the tools you already use.
What you will be able to do
- Pick a chart type that matches the comparison you need to show
- Remove clutter so the main point is visible in seconds
- Use color and labels to direct attention honestly
- Build a small dashboard page around three to five questions
- Spot misleading axes, scales and aggregations in other people's charts
