This visualization shows the distribution of horsepower across ten car models, using a horizontal stacked bar chart where each bar represents a model and segments show the proportion of its power falling into five ranges from below 200 to above 800 horsepower. The chart uses a divergent color scale from green through purple, blue, yellow, and red, with model names on the y-axis and percentage on the x-axis. Built with d3.v7, it employs d3.stack() to create the stacked layout, d3.scaleBand() for the categorical y-axis, and d3.scaleLinear() for the continuous x-axis. Interactive tooltips display the exact percentage for each segment on mouseover, with data sourced from a CSV file containing proportional values that sum to one per car.
