{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart visualizes temperature data from San Francisco over one week, using multiple colored lines to differentiate regions. The chart encodes profit values on the x-axis and segment categories on the y-axis, with color mapping to region through an ordinal scale. Built with D3 v5, the visualization uses `scaleLinear`, `axisBottom`, `axisLeft`, `line` with `curveBasis`, and `nest` to group data by region. A custom `colorLegend` component displays the color scale, while the SVG rendering includes gridlines, axis labels, and a title.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6c5a4f905b7d4970bbe9093dc2822883?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
