{"version":"1.0","type":"rich","title":"Word Cloud","description":"This example visualizes COVID-19 home-care guidance as a word cloud, with terms like “medical” and “breathing” scaled by frequency. A word counter filters stopwords, then `d3.layout.cloud` (from cloud.js) computes the layout, sized using a linear `d3.scale.linear` mapping counts to font sizes from 10 to 100 pixels. The SVG output uses `d3.scale.category20` for colors, random 90-degree rotations, and Impact font, rendering text elements positioned by the layout’s `draw` callback.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c109b071c4d54593a66c2df04301297c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
