{"version":"1.0","type":"rich","title":"Responsive Chord","description":"A Responsive Chord diagram visualizes bilateral trade flows between countries, using curved chords to show the direction and volume of exchanges between pairs of sellers and buyers. The matrix-based layout positions entities around a circular arc, with chord thickness proportional to flow values read from a CSV file. Built with D3 v3, the code employs `d3.layout.chord` to compute the layout, ordinal color scales for categorical grouping, and custom tooltips for hover details. The visualization also implements fade effects on non-hovered chords to focus attention on specific relationships.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-8e5bd54fffed0b26d2c0ed244920c8d5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
