This example demonstrates axes that adjust to the browser window size, with a simple bar chart showing grocery item prices. A resize event listener calls a render function that rebuilds the visualization using the updated viewport dimensions. The implementation applies D3 v5’s margin convention to compute inner dimensions, then uses `d3.axisBottom` and `d3.axisLeft` with dynamic tick counts based on pixel density. Axes are labeled via custom functions, and SVG elements are updated through data joins, ensuring the chart remains responsive.
