{"version":"1.0","type":"rich","title":"Activity 6 Task 4","description":"This example shows a bubble chart that visualizes spatial data by mapping x and y coordinates to a scatterplot and a third size value to the radius of each circle. The chart loads CSV data from a GitHub repository using D3 v5’s `d3.csv` method, then renders the bubbles as SVG circles with a skyblue fill and semi-transparent opacity. It uses `d3.scaleLinear` for the x, y, and radius scales, and displays axes via `d3.axisBottom` and `d3.axisLeft`, with explicit axis labels. The SVG canvas is fixed at 800 by 600 pixels with defined margins.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/34f02a986c9f46d2a893e47765bf9157?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
