Data Visualization

You’ve just received your sales numbers for the past month and you want to use them to help you understand the impact they are having on your revenue and inventories. What do you do? Do you print them out and start the laborious process of reviewing the numbers and comparing them to previous reports? Do you throw them in spreadsheet and use some formulas? While these methods could yield some results, the process can get laborious and you will only find what you’re looking for.
