{"version":"1.0","type":"rich","title":"Line chart - Nghia Dang","description":"This line chart visualizes temperature readings over time across multiple districts, with each line color-coded by district and labeled through a custom legend. Built with D3 v5 and rendered as an SVG, the chart uses `d3.scaleTime` and `d3.scaleLinear` for the axes, `d3.line` with `d3.curveBasis` for smoothed trajectories, and `d3.nest` to group data by district. Data comes from a remote CSV file parsed with Day.js for date handling. The visualization includes rotated axis labels, gridlines, and a title.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b99176d8263c481f93edd071385bfd99?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
