This visualization presents a convolutional neural network architecture as a sequence of labeled boxes representing layers such as input, conv2d, maxpool, flatten, and fully connected layers, with each box annotated by its output dimensions. The design uses D3.js v7 to draw SVG rectangles and text, with utilities that generate each layer box and connecting lines. Styling for colors and geometry is defined separately, while the main script orchestrates the layout by advancing an x-coordinate between layers.
