Starting from IDA v6.2, the callgraph of a program can be displayed in a graph form.
In the proximity view, the current address, the callers and the callees are represented as a collection of nodes linked together with edges. Nodes represent functions and data references (global variables, strings, etc..) and edges represent code or data cross-references between them.
To open the proximity view press the '-' key to zoom out and switch to the callgraph of the address under cursor.
Only the address names (function names or data labels) are displayed in the proximity view, but not the disassembly, nonetheless, hovering the mouse over a node will display brief disassembly listing in a resizable hint window. To see the complete disassembly listing switch to text or graph mode by pressing '+' or Space respectively.
When disassembling new files, IDA will display a dialog offering to switch to proximity view when applicable. It is possible to turn off this dialog and not show it again.
In the proximity view there are 3 types of nodes: Function nodes, data nodes and auxiliar nodes. Function nodes are rectangular and they have a toolbar. Those nodes are used to display the callers or callees of the current central node (or any of his parents or children). Data nodes are rectangular nodes (without a toolbar) and they are used to display the data references (global variables, strings, etc...) to/from the current central node or any of his parents and children.
