This example demonstrates a minimal SVG visualization scaffold that renders an empty chart area using D3 v5. The code imports core D3 modules including `select`, `csv`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom`, then initializes an SVG canvas with fixed dimensions. A `render` function is defined but contains commented-out attempts at creating color scales, band scales, and SVG rectangles, with the actual rendering logic disabled. The visualization only calls `render` with an array of three numbers, resulting in no visible output on the page.
