This example demonstrates a minimal D3 v6 starter template, rendering a set of 15 circles arranged sequentially in an SVG canvas. The visualization shows how to select an HTML body element, append an SVG, and bind an array of data to circle elements using the data join pattern. The code uses d3.select, d3.range, and the `.enter()` method to create circles with a fixed radius of 100 pixels. The SVG dimensions are set to match the browser window, though the variable name `h` and the attribute method contain typos that would prevent the chart from displaying correctly.
