{"version":"1.0","type":"rich","title":"Median PM2.5 daily concentration","description":"This line chart visualizes median PM2.5 daily concentration across months, with a smooth curve connecting data points. The y-axis measures concentration levels, while the x-axis represents months from January through December. Built with D3 v5, the code uses `scaleLinear`, `scaleTime`, `axisLeft`, `axisBottom`, and `line` with `curveBasis` to generate the SVG path. Data is loaded from a CSV file hosted on GitHub Gist, and the chart includes styled grid lines and axis labels. The rendering approach uses an SVG element with margins defining the plotting area.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c724941f8aa14080bba9e1f80042f81a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
