I am doing a survey. I need to make a flow chart to show when and where I collected the data from. So at the top it would "Population" then branches out into the days of the weak, each branching out into time of day etc. I will have 45 leafs (end enteries) and I was wondering what computer program does this nicely. I tried using Visio but it screws up because the size of the boxes doesn't get smaller for each level I go down.
