Just a Basic Pie Chart Maker
Save and load to simple txt fie and Save picture to Png.
Uses a TListbox to enter the values into.
Select your own sector colors.

Made the following changes:
Added labels for labeling the values on the chart.
These label positions can be changed with mouse click and drags.
Dynamically placing these labels when the font size of the labels is changed.
I made the centroid of the Value labels move along radial mid-lines of each sector.
Saving the labeled values on the Pie Chart to png.
Thanks to (
https://stackoverflow.com/questions/43738888/save-imageenview-and-a-label-on-it-as-png-in-delphi
) for the idea on how to do it.
Enjoy.

Actually had an idea of using a TColorListBox instead of a Normal TListbox.
but things are kinda getting real screwed. Ouch!
