Php pie chart function

Let me introduce myself first. I am a newbie. at that time, I learned php purely for the sake of perfunctory leadership. let's make a statistical chart. I was originally learning asp, and suddenly I was not suitable for business transfer, but php is really powerful, huh, I can't leave him anymore.

I was a newbie. at that time, I learned php purely for the sake of perfunctory leadership. let's make a statistical chart. I was originally learning asp, and suddenly it was not suitable for business Conversion. However, php is really powerful, well, I can't leave him anymore. no, it's a pie chart or a column chart. but there are still many titles that I won't know. I hope you can give me more advice and talk a lot about it, I also think it is writing a letter

The boss reminded me that there was no way. The pie chart function was released.
