Hex Ray has introduced a decompiler API as part of IDA v6.6. Is there any plugin which displays the detail Abstract Syntax Tree (AST) produced by the decompiler graphically?
vds5 plugin in the Hex-Rays SDK.

It is also added into the right-click menu. * * To display the graph, we traverse the ctree and build * a gdl_graph_t object. Then we use gen_gdl() function from IDA * to create a GDL file from this object. Finally, we call * wingraph32 to display the graph on the screen. * */
