{"version":"1.0","type":"rich","title":"Overlapped Barchart5","description":"This example visualizes health survey data across time periods using a series of overlapping, semi-transparent rectangles. The bars are positioned along a time axis from the start to the end date of each survey, with their height reflecting the reported percentage value. A red line connects the midpoints of these intervals to highlight the trend over the years. The visualization is rendered as an SVG using React and D3.js v6, specifically employing `d3.scaleTime`, `d3.scaleLinear`, `d3.line`, and JSON data loading via `d3.json`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/86a9904c179c460c84a8260917d2ace5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
