{"version":"1.0","type":"rich","title":"QUESTION-4(TASK-4)","description":"This bubble chart visualizes product sales across three regions, with Europe on the x-axis, Asia on the y-axis, and North America represented by bubble size. Each circle’s color distinguishes a product category, and hovering reveals exact sales figures via a tooltip. Built with D3 v7, the code uses `d3.scaleLinear` for axes, `d3.scaleSqrt` for bubble radius, and `d3.scaleOrdinal` with `d3.schemeCategory10` for colors. Data is loaded from a CSV file using `d3.csv`, and the SVG is rendered with axes, labels, and interactive event handlers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f1280b7992e64b3f83baac7e45c83312?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
