If you want a pictorial definition of flux in terms of field lines, then the definition could be "the number of electric field lines emerging out of a conductor", (bb1) perpendicular to the conductor's surface, (bb2) per unit surface area of the conductor.

The field lines are more properly called flux lines. The closer they are drawn together, the stronger the field
