{"version":"1.0","type":"rich","title":"Assignment 2_Bubble chart","description":"This bubble chart visualizes the correlation between make cost, selling price, and profit percentage for various car brands. The data, sourced from `profits.csv`, is rendered as an interactive SVG using D3 v7, where bubble size encodes profit percentage and color distinguishes car brands. Implemented with `d3.csv`, `d3.scaleLinear`, and `d3.scaleOrdinal`, the chart displays axes for selling price and cost, with a legend for profit percentage and brand colors. Hovering over a bubble triggers a tooltip showing the brand name, supported by custom `showTooltip`, `moveTooltip`, and `hideTooltip` functions on `mouseover`, `mousemove`, and `mouseleave` events.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/23f491f86f094e8d92f34459895e510e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
