Few years ago I too "mined data" ( this word sounds ethical ) the data from MTNL site. I got the record of every single person who have landline number in delhi. ( Actually I just wanted to see the bill amount ) but they showed me everthing. ;) Though I didn't made such graphs. Whats's more in one of the site I was able to clear my bill by paying as much I like. That means if my bill was 1000/- then by just paying 100/- I would get the confirmation of 1000/- bill pay. :)
