{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays one week of temperature data in degrees Celsius from cities around the world, sourced from Data Canvas - Sense Your City. Each city appears as a separate smoothed line, color-coded using a categorical scale, with time on the x-axis and temperature on the y-axis. The visualization uses D3 v5 with SVG rendering, employing `d3.scaleTime`, `d3.scaleLinear`, `d3.line` with `curveBasis`, and `d3.nest` to group data by city. A custom color legend and gridlines with axis labels complete the chart.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c7e0625a2392496f9ab26da478fe5daa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
