{"version":"1.0","type":"rich","title":"Line Chart","description":"This line chart displays violent crime rates per 100,000 people for each U.S. state from 2000 to 2019, using data from the CORGIS dataset. Each state is represented by a colored line, with a color legend on the right for identification. Built with D3.js (v7), the visualization uses `d3.scaleLinear` for axes and `d3.scaleOrdinal` for color assignment, rendering paths and hover-able circles in SVG. The `d3.legendColor` API adds the threshold legend, and tooltips reveal exact values on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a9d567734f894b38ad015c8d665e0440?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
