This example demonstrates loading and parsing CSV data using D3’s `d3.csv` method, displaying a summary of the dataset’s size, row count, and column count in a preformatted text block. The page also includes a static SVG rendering of a quantum circuit with qubits (Q0–Q2) and gates like H and CNOT, drawn using basic SVG shapes. The visualization is built with React and D3 v7, using `d3.csvFormat` to compute the data’s byte length for the summary. The underlying data source is a CSV file containing CSS named colors.
