About this course
A chart can contain the correct numbers and still leave its audience unsure what matters. Anand Narayanan introduces data visualization as a communication process, bringing together information design, narrative structure and deliberate choices about charts and color.
The five-part overview presents a twelve-step process, a visual-narrative formula and a chart library. It then considers context and design choices that influence how readers interpret a display, rather than teaching the menus of one particular software package.

No prerequisites are listed. This is a technology-agnostic introduction, useful before committing to a dashboard tool or as a way to reconsider an existing presentation. It is not a software workshop or a complete data-analysis curriculum.
The course description also promotes a separate one-day masterclass. The free listing itself contains approximately 49 minutes of instruction; the larger event is not included. For a practical next step, examine a chart you already use and identify its question, audience and most important comparison before changing its appearance.
Frequently asked questions
Do I need Tableau or Power BI?
