How To Do Graphs?

There are several types of graphs, such as using a pie chart, a circle with different colours indicating the percentage of each item.  Or if showing growth or decline, you can use a box chart with little squares and draw a line through each showing either decline or increase.  There is also the ones that you see on TV for cell phones, bar chart.  More bars in more places.  These are like towers showing ups and downs - I hope this is what you mean and not skin graphs, that is a whole other story of removing parts of skin and replacing them to another area to promote skin growth etc.
