AnyChart JavaScript Gantt Chart is optimized for high-volume rendering, handling large hierarchical datasets with smooth scrolling and zooming on the timeline.
This sample loads a tree-structured JSON dataset containing approximately 10,000 data points into a project Gantt chart. After drawing, the chart zooms to a focused date range (February to April 1987) so that individual task bars remain readable even in a dense schedule. The sample demonstrates that the Gantt engine maintains responsive navigation and rendering performance at scale.
See the Gantt Chart documentation for all configuration options.
