Is it possible to construct the histogram graph given the variance and the mean value of the samples?

You can only do that for very specific theoretical distributions such as the Normal distribution (and then again, you would represent a density function rather than a real histogram).
For regular data, two numbers are not enough to represent hundreds or thousands of values.

No. Consider $\{0\}$ and $\{0,0\}$. Both have mean and variance $0$ but different histograms.
