Creating a clickable image map. This JAVA applet, when called from the 2DB environment, displays the image of the experiment and the list of items that led to identifications. This list can now be correlated to the picture by clicking an item in the list and then defining an area on the picture. Additional information, such as mass and pI for the specific area, can be entered. At any point, the changes can be uploaded to the database and will persist there. Defining these hotspots essentially creates a clickable image map which effectively visualizes the data in the database.
