Fork of Bar chart with a Sequential color scale New
This bar chart displays the average horsepower for seven car brands, sorted in ascending order and colored with a sequential red scale that maps horsepower values to color intensity. Built with D3 v6, the visualization uses `d3.scaleBand`, `d3.scaleLinear`, and `d3.scaleQuantize` to position and color the bars, while a tooltip appears on mouseover. The rendering is SVG-based, with axes, a color legend, and animation effects, drawing data from a CSV file named `barchart.csv`.
