Dalliance is an interactive genome viewer which runs directly in your web browser. If you are running a modern browser with Javascript enabled, you should see it running on this page:
The aim is for a high level of interactivity. Drag to scroll ("Google Maps" style), or try a panning gesture if your input device supports this. You can add more data from the DAS registry by clicking the "Add track" button in the toolbar, or follow the links in the sidebar to browse other genomes or more data.
