This example demonstrates loading and parsing a cleaned Disney characters CSV dataset with D3.js v7, displaying summary statistics such as total rows, distinct movies, average popularity score, and debut year range in interactive cards. It also renders a preview table showing the first eight rows of the data, including a color swatch rendered inline for the `color_hex` column. The visualization uses `d3.csvParse` with custom row accessors to coerce numeric fields, along with `d3.mean`, `d3.extent`, and data-join methods like `selectAll().data().enter().append()` to build the SVG and HTML elements.
