Scatterbrain
A scatterplot displays the relationship between a vehicle’s signal score and its weight percentage, using data from the UCI Auto MPG dataset. Red semi-transparent circles are plotted on a linear scale, revealing a dense cluster with no clear correlation. The visualization is built with D3 v5, using `scaleLinear`, `axisBottom`, `axisLeft`, and `csv` to load and render the data as SVG circles with an opacity of 0.3.
