{"version":"1.0","type":"rich","title":"assign3-4","description":"This bubble chart compares cereal manufacturers by plotting their products' ratings against sodium levels. Each bubble's position encodes the rating (x-axis) and sodium content (y-axis), while its radius represents calorie count through a linear scale, and its color indicates the manufacturer using a categorical ordinal scale with the `schemeSet1` palette. The visualization, built with D3 v7, uses `d3.scaleLinear`, `d3.scaleOrdinal`, and `d3.axisBottom`/`d3.axisLeft` to render the SVG, with legends for both bubble size and manufacturer colors. Data comes from a local CSV file loaded via `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a7c29207b6414fdab86bc05f8bb9a5ee?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
