{"version":"1.0","type":"rich","title":"activity6_tutorial4","description":"This bubble chart visualizes car performance by plotting horsepower on the x-axis and torque on the y-axis, with each circle’s radius scaled to horsepower using `d3.scaleSqrt` and colored by manufacturer via `d3.scaleOrdinal` with `d3.schemeCategory10`. The chart renders axes with `d3.axisLeft` and `d3.axisBottom` and adds a legend using a custom `renderLegend` function. Data is loaded asynchronously from `data.csv` and processed in `useData.js`, with the SVG built using D3’s selection and `.join` operations.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ac660246bc8b4d549cda8526d2e1dbb7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
