Turns data into charts that actually communicate something. Walks you through choosing the right visualization type based on what you're trying to show (comparisons, trends, distributions, relationships), then applies solid design principles like maximizing data-ink ratio and ensuring colorblind-safe palettes. The accessibility guidance is practical, reminding you not to rely on color alone and to make interactive charts keyboard navigable. Also covers responsive considerations, which matters when your beautiful desktop dashboard turns into an unreadable mess on mobile. The chart selection matrix alone saves you from the classic mistake of throwing a pie chart at everything.
