Using Charts To Help You With Problem Solving
It is well known and well publicized that graphs and charts can be used to demonstrate and present data visually to an audience. The visual of the data can highlight points of data quicker and easier than just numbers in a table. One thing that I have noticed over the years is that when talking […]
