This example visualizes the co-occurrence of hashtags from a dataset of tweets, showing clusters of related tags through an interactive network layout. It uses D3’s `d3.forceSimulation` to position nodes and manage collision, while links are drawn with SVG lines. The data is loaded from a CSV file, and user interaction, such as dragging and collision behavior, is implemented via force settings and event listeners. The visualization also includes a hover effect that highlights a node’s connections, using D3’s selection and transition methods to update styles dynamically.
