{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"A line chart displays one week of temperature data for multiple cities around the world, with each city represented by a smooth, color-coded line. The chart is rendered as an SVG using D3 v5, with axes, gridlines, and a color legend positioned to the right. Data is loaded from a CSV using `d3.csv` and processed with `d3.nest` to group measurements by city. The lines are generated with `d3.line` and `curveBasis`, while `d3.scaleTime`, `d3.scaleLinear`, and `d3.scaleOrdinal` handle scaling and colors. The dataset originates from the Data Canvas - Sense Your City project.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a242e40120f44bcbb621264985acd139?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
