Foundations

Download Tableau, get it installed, and click around the workspace before the first taught lesson.

Connect Tableau to a CSV file and get oriented on the Data Source page -- including the choice between a Live connection and an Extract.

Picking up right after your data is loaded, understand Tableau's Physical Layer and how to build joins (inner, left, right, full outer) between tables, how joins differ from Relationships in the Logical Layer, and how to use Join Calculations to create composite keys when tables lack a shared column.

Learn to distinguish Dimensions (qualitative, used to segment data) from Measures (quantitative, aggregated), understand how discrete (blue) vs. continuous (green) pills change chart behavior, and see how toggling a date field between discrete date-parts and a continuous timeline switches between grouped bar charts and a single flowing line.

Build your first visualizations using bar and line charts. Master the Tableau Marks Card (Color, Size, Label, Tooltip) to highlight performance differences, understand how discrete (blue) vs. continuous (green) fields change Marks Card behavior, and learn to limit labels (e.g., Min/Max only) for clean, readable visualizations.

Build a scatter plot in Tableau to compare two continuous measures, encode a third and fourth dimension using Size, Color, and Shape, switch marks to Filled Circles, and fix overplotting with Opacity and Border adjustments.
