As ${\mathrm{AgNO}}_3$ is added to solution, $\mathrm{KCl}$ will be displaced accrding to following reaction $${\mathrm{AgNO}}_3(aq)+\mathrm{KCl}(aq)⟶\mathrm{AgCl}(s)+{\mathrm{KNO}}_3(aq)$$ For every mole of $\mathrm{KCl}$ displaced from solution, one mole of ${\mathrm{KNO}}_3$ comes in solution resulting in almost constant conductivity. As the end point is reached, added ${\mathrm{AgNO}}_3$ remain in solution increasing ionic concentration, hence conductivity increases.
