This example displays tabular data on heating systems, showing values for floor area, energy consumption, and CO2 emissions across seven fuel categories. It builds an HTML table using D3.js v3’s `d3.csv` to load the data and `d3.select` with `.append` to create the table, headers, and rows. The table features zebra striping and responsive design for mobile devices. Column headers are created from the dataset’s keys, and each cell shows its corresponding value with a `data-th` attribute for labeling on smaller screens.
