A Timeline Chart places events and durations along a horizontal time axis, making it easy to compare parallel processes and track progress over time.
This sample visualizes the Pfizer-BioNTech COVID-19 vaccine development alongside milestones from Moderna, Johnson & Johnson, and Novavax. Color-coded range bars represent trial, review, and approval phases, while moment series above and below the axis mark key facts and dates for each vaccine. Text markers, custom tooltips, and a scroller provide full context from JSON-loaded data.
