{"version":"1.0","type":"rich","title":"Gantt Chart","description":"This Gantt chart visualizes project tasks, including development, coding, promotion, and celebration phases, as horizontal bars positioned along a linear time scale. The chart uses D3 v5 to parse dates with `d3.timeParse`, scale time with `d3.scaleTime`, and render colored rectangles within an SVG container. Task categories are distinguished by a gradient color scale using `d3.scaleLinear` with HCL interpolation. Hovering over a task reveals a tooltip with its name and duration details, while the grid and labels are also generated with D3.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5e40516f9a6a482a82636344917a8811?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
