{"version":"1.0","type":"rich","title":"Area Chart Visualization","description":"This area chart displays Google’s annual user counts from 2011 to 2021, emphasizing the upward trend through a filled region beneath a smooth curve. The visualization is built with D3 v5, using `d3.line` and `d3.area` generators with a `curveBasis` interpolation to create smooth paths. It loads CSV data from a GitHub gist, maps years to a linear x-scale and user counts to a linear y-scale, and renders axes with gridlines as SVG. Styling is applied via external CSS, with distinct colors for ticks, labels, and the area fill.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e7eec0ddc2244117ac15066981bb0a72?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
