{"version":"1.0","type":"rich","title":"Overlapped Barchart3","description":"This visualization displays five time periods as overlapping horizontal bars on a timeline, with each bar's width representing the date range and height reflecting the data value (a percentage). The chart uses React to manage state and D3 v6 APIs (`d3.json`, `d3.scaleTime`, `d3.scaleLinear`) to parse dates from a JSON file (`timeperiodv2.json`) and map them to SVG rectangles. The bars, drawn in semi-transparent green, overlap to highlight how different survey periods (e.g., NFHS3, RSOC, CNNS) compare chronologically and by value, while axes and grid lines are generated from D3’s tick functions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d8c08f609c864403b55b8cd8aa9cb1f8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
