The hash that you extracted really contains only one linear array, which is probably not suitable for what you want to do. On the other hand, I provided you with a means to get an array of arrays, which is what you asked for in the first place, did you look at the AoA I obtained? Is it suitable for your purpose? As for GD::xxx, I do not know these modules nand can't help further.
