This tool will generate a histogram representing the distrinutions of each numerical column. Each column should have a descriptive header with no spaces, which will be used in the plot legend to represent the corresponding column (group).

Input data example:
ID  Cond_A Cond_B
gene_A  10  15
gene_B  8   12
gene_C 10   15
gene_D  6   9
gene_E  9   13.5
gene_F  8   12
