This example visualizes the Body Mass Index (BMI) of ten individuals from a CSV dataset, using a bar chart to compare each person’s BMI value. The chart shows the BMI for each name, with bars representing the numeric BMI values. The visualization is built with D3.js v7, rendering SVG elements. It uses `d3.scaleBand` for the categorical x-axis and `d3.scaleLinear` for the y-axis, with `d3.axisBottom` and `d3.axisLeft` to display the axes. The data is loaded from the provided CSV file, and each bar’s height reflects the BMI, colored in steel blue.
