The XperimentR popup menu when clicking on a Biosource. When the user clicks on a node in the graph a popup menu appears. The items in the popup menu are constrained by the type of node that is being selected (biosource, container or assay). As the user moves the mouse over the icons a popup will display notifying the user of the name. To add an item the user simply drags the item from the popup menu to the graph canvas.
