{"version":"1.0","type":"rich","title":"Gantt chart","description":"This Gantt chart displays the time spans of three items, A, B, and C, as horizontal bars along a shared timeline, with each bar’s length representing its duration. The chart uses React with D3 v7, rendering to SVG via a single `<svg>` element. It leverages `d3.scaleTime` and `d3.scaleBand` to map dates and categories to positions, and `d3.axisTop` with yearly ticks to label the time axis. The data comes from a local JSON file read at runtime.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0b18cc92de8f46c6afab5f5317adbd23?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
