This example shows a simple scatter plot of 100 randomly generated points, each positioned on a 500-by-500 pixel SVG canvas. The visualization uses D3.js v4 scales and axes to map linear domains to screen coordinates, with red circles drawn for each point. The code appends an SVG group to the page, translates it by a 40-pixel margin, and uses `d3.scaleLinear` for both the x- and y-axes, which are rendered via `d3.axisBottom` and `d3.axisLeft`. Data is created in a loop using `Math.random()`.
