how can we crate this Graph.

Create custom button ‘Send Followup’ on Account. When button is clicked it should display a new UI with list of related contacts and a selection checkbox against them. List of contacts should display columns Name, LastModifiedDate, Email, Phone. VF Page should have button ‘Create Task’ Once user selects contacts from list and click on ‘Create Task’ button; task should be created corresponding to that contact with following details – Task owner as Contact Owner Task subject ‘Follow Up’ Task due date = Today() + 3 Days.
