This example visualizes the foundational concepts of blockchain technology, breaking down its four core characteristics—distributed, trustless, immutable, and accountable—into a structured mind-map layout. The visualization organizes the text from the accompanying Markdown file into hierarchical nodes, with each characteristic branching into its supporting mechanisms like consensus, block chaining, and cryptography. It uses a force-directed graph rendered with D3’s `d3.forceSimulation` to position the nodes, while the textual content is drawn directly onto an SVG canvas. The data is parsed from the plain-text Markdown structure, preserving the nested bullet hierarchy as the visual tree.
