This visualization displays email communication patterns within the DBL Group 45BD workgroup, using a custom arc diagram to show relationships between employees. It plots each unique email address as a node along a horizontal axis, with curved paths connecting senders to recipients, colored by job title using the d3-scale-chromatic color palette. The code filters data to only show top-level roles like CEO, President, and Manager, and limits the dataset to 1000 records. Built with React and SVG, it implements zoom functionality through d3.zoom and reads CSV data using d3.csv.
