This example visualizes the maximum life expectancy of 15 dog breeds using a horizontal bar chart rendered as SVG. The chart displays each breed’s name along the y-axis and a numeric scale along the x-axis. It uses React with hooks (useState, useEffect) to load and parse CSV data via d3.csv, then d3.scaleBand and d3.scaleLinear to position bars and ticks. Grid lines and axis labels are drawn manually with SVG elements, while d3.max and d3.format support the data domain.
