{"version":"1.0","type":"rich","title":"A7 Multi-Line Chart","description":"This chart visualizes violent crime rates per 100,000 people across U.S. states from 2000 to 2019, using data from the CORGIS dataset. Each state is shown as a multi-line path with colored dots for individual data points, and hovering reveals exact values. The visualization is built with D3 v7, using `d3.csv` for data loading, `d3.line` for path generation, and `d3.legendColor` from the d3-legend library for the color legend. Axes are rendered via `d3.axisBottom` and `d3.axisLeft`, with an ordinal color scale distinguishing states.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5a42045defbb4868b9558fd406eaa616?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
