This example shows a static SVG scene with a red square and an orange circle, followed by a D3 script that generates additional blue and green rectangles whose positions and heights derive from an array of five numbers. The code uses the D3 library (version 3.5.5) to select the SVG, append a rectangle, and bind the data array to a `selectAll("rect")` operation, setting each rectangle's `x`, `y`, and `height` attributes through anonymous functions. The rendering is purely SVG-based, with no interaction or animation.
