{"version":"1.0","type":"rich","title":"ICE 7- Area Chart","description":"This area chart visualizes the average insurance charges for each age group, using a steelblue filled area to show the trend across ages. Built with D3.js v7 and React, the code fetches a CSV from a GitHub gist, aggregates the raw data by age, and computes average charges. It uses `d3.scaleLinear` for the x and y axes, `d3.area` to generate the area path, and `d3.axisBottom` and `d3.axisLeft` for the axes. Interactive tooltips appear on hovering over the data points, which are drawn as SVG circles. The visualization is rendered as a static SVG with no animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9dd09bcad00e4a559219901fe9a949b4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
