I'd like check the visualized error per cell.
Is there any module in deal.ii that enables this...?


Yes, you just need to create a vector with as many entries as there are cell (e.g., the output of VectorTools::integrate_difference) and attach that to the DataOut object you have. step-27 shows how to do that, but it in essence works just like for vectors that have as many entries as there are DoFs.
