如何根据简单leaders.xml文件的分数创建图形系统？

Question

I have this xml file called leaders.xml as below. When the "student" end with my test the score it is shown to him and saved into that file. What I do is to show the students in a top 10 order but I need to create something also like a graph. The graph should contain the name of the student and the score. I don't mind if it is a bar graph or something simpler. All the questions are 10.

What do you suggest me to do? All of your examples/code/scripts are highly appreciated. Thank you

You can use google chart api to display charts. You just need to give paramiters in the url and use that url in image source. Refer this
