Can we draw flowcharts through PLSQL

  Hi All,Is there any feature in oracle where in using the plsql code we can generate flow chart.

that is 

If our code is 

(this code mainly add the numbers if first number is greater)

declare

firstnum number;

second number ;

total number;

your_action varchar2(100):='ADD';

begin

if your_action='ADD' then

total:=firstnum+second;

else 

total:=firstnum-second;

end if;

end;

Then it should generate the flow chart.

Please let me know your views.

Also if its not possible with PLSQL , Is there a way to use JAVA and get the flowchart drawn onto some word document.

With Regards
