{"version":"1.0","type":"rich","title":"activity 7.2","description":"This area chart displays monthly visitor numbers for a full year, with values rising from 1,000 in January to a peak of 2,700 in December. The visualization uses D3.js version 6 with an SVG rendering approach, employing `d3.area()` to generate the filled path, `d3.scalePoint()` for the categorical month axis, and `d3.scaleLinear()` for the visitor count axis. Axes are rendered with `d3.axisBottom()` and `d3.axisLeft()`, with rotated month labels and explicit axis titles. The chart includes a steel-blue fill and uses hardcoded sample data embedded in the script.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/645fb130e648401e940703657fb293bd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
