A bar chart displays the values of three fruits (apple, banana, pineapple) from a CSV file, with each bar colored red, green, or blue. The chart uses D3 v4's `d3.select`, `d3.csv`, `d3.scaleBand`, `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and `d3.scaleOrdinal` to render an SVG visualization with rotated x-axis labels and a fixed y-axis range from 0 to 100.
