{"version":"1.0","type":"rich","title":"Untitled","description":"This example visualizes state population trends from 1910 to 2010 using colored lines for California, Michigan, and Texas. Hovering over the chart reveals a tooltip and a vertical line showing the exact population values for each state at that decade. The visualization is built with d3.scaleLinear, d3.line, and d3.axisBottom/axisLeft, and uses d3.json to load data from a JSON file. It renders as SVG, with a custom tooltip div positioned via d3.event coordinates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a7e0d3483aa6476fa223b531438c2c57?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
