{"version":"1.0","type":"rich","title":"Activity-6 task-4 question-4.9","description":"This bubble chart visualizes transaction data across eight spending categories, plotting average transaction amount on the x-axis, transaction count on the y-axis, and total spending as bubble radius. Each category is color-coded using `d3.scaleOrdinal` with `d3.schemeSet2`. The visualization uses D3 v7 to load CSV data, render SVG circles, and provide interactive tooltips on mouseover. Axes are created with `d3.axisBottom` and `d3.axisLeft`, while `d3.scaleSqrt` maps total amounts to proportional bubble sizes for easy comparison of spending patterns.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9e8c07b888da4e31b1022c1398db833c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
