How to create a pie chart for my case?

[#1]

I am supposed to create a pie chart based on the percentage of fitment.If the percentage of fitment is 75 it should appear in yellow color in the pie chart,If  fitment is 100 then it should appear in green,If fitment is 50 then red.This is the way I want. But the I loaded the fitment column using load inline like follows

LOAD * INLINE [

    GID, Fitment

    484018, 100

    483996, 75

    484093, 75

    484103, 100

    468420, 100

    483119, 100

    483105, 100

];

Now  I have to create a pie chart.Please help to do this.
