This example shows a filterable data table that displays website assessment records across time periods. A dropdown menu lets the user select a frequency—Daily, Weekly, BiWeekly, or Monthly—which updates the table to show the latest 12 columns of data for that interval. The code uses D3.js v7 modules including `csv`, `select`, `group`, and a custom `menu` component built on `dispatch`. Data is loaded from a CSV file, then grouped by website name and sorted by date, with column headers dynamically generated based on the selected frequency.
