{"version":"1.0","type":"rich","title":"Bubble Chart","description":"This bubble chart visualizes the frequency and emotional associations of words from two different decades of Italian song lyrics, selectable via a dropdown menu. Each circle’s area encodes the word’s frequency, while its color maps to an emotion category (e.g., gioia, paura, tristezza) using a categorical color scale. The visualization uses a d3.pack layout to hierarchically cluster the words, with labels clipped inside each circle, and tooltips showing the exact value. The chart is rendered as an SVG using D3 v4, allowing hundreds of words to be compared at a glance in a compact space.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-f6a26140fd2e69e7ab2851086f07033c?mode=embed\" width=\"960\" height=\"960\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":960,"cache_age":3600}
