This example renders a markdown table as a simple data visualization, showing the relationship between two columns of text content. The code uses D3.js to parse the table structure and display the cells in a grid layout. It relies on standard D3 selection and data-binding methods to map each row and column to positioned text elements. The visualization draws directly from the gist’s embedded markdown data, converting the header and body cells into a clean, readable chart without additional processing or external data sources.
