{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays one week of temperature data in degrees Celsius for cities worldwide, sourced from Data Canvas - Sense Your City, with each line representing a different city. The visualization aggregates the data using a nested hierarchy and renders the result as SVG paths, with color encoding to distinguish between cities. Built with D3 v5, the code uses `scaleTime`, `scaleLinear`, `scaleOrdinal`, and `nest` to process the data, while `axisBottom`, `axisLeft`, and a custom `colorLegend` module handle the axes and legend. The chart includes a time-based x-axis, a linear y-axis, and a categorical color scale with a legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0cefefc52cbd46acb74354259883fbcf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
