This fork of the D3 v3 word cloud example visualizes family names and first names from local JSON data. The code loads data using `d3.json`, filters and sorts entries by frequency, and displays the top 120 terms as an SVG word cloud via `d3.layout.cloud`. Buttons in a toolbar allow switching between the `Fam_Totaal.json` and `VN_Tot.json` datasets. The visualization uses a linear scale, random rotation, and category20 color encoding to render text within an 800 by 400 pixel container.
