{"version":"1.0","type":"rich","title":"Assignment #5 Bubble Chart ","description":"This bubble chart compares fuel economy (mpg) against the number of cylinders for eight car models from a CSV file, with each car positioned along the x-axis and its economy value plotted on the y-axis. The visualization uses D3 v7's `scaleBand` for the categorical x-axis, `scaleLinear` for the y-axis, and `axisBottom`/`axisLeft` to render axes. Instead of traditional bars, it draws a line path using `d3.line`, mapping car names to x-coordinates and economy values to y-coordinates, with the y-axis explicitly sized to cylinder counts via a second linear scale. The SVG output is styled with steelblue strokes, and the chart title is displayed above the plotting area.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/734b07c30e1e4f6380e7e2cf4a9b3c67?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
