{"version":"1.0","type":"rich","title":"Area_chart_Niharika","description":"An area chart visualizes pollution percentages by year, filling the space beneath a smooth curve with orange. The data comes from a GitHub gist and is loaded via `d3.csv`. The chart uses `d3.scaleTime` for the x-axis and `d3.scaleLinear` for the y-axis, with axes rendered using `d3.axisBottom` and `d3.axisLeft`. The area path is generated with the `d3.area` generator and a `curveBasis` interpolation, all drawn as SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/050382f4c99f4c34a1270620e4f1766a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
