Response Visualizations in Postman
summary
Shows how Postman renders response data via the pm.visualizer API by taking a template plus the response and injecting HTML into a webview/iframe (Electron or Artemis). Uses pm.visualizer.set, a handlebars template, and libraries like Chart.js and D3 to plot charts and maps; demo plots UK ATM lat/longs using a map tile provider and an echo endpoint to build a simple messages view. Public workspace with forkable sample visualizations and devtools-based debugging are available.
