Pie chart conceptual problem

Dear all,
i have indexed a CSV file. now i want to generate a pie chart of it same as the image attached with this post.

i tries a lot but failed to produce such chart.
can anyone guide me how can i generate such a chart from such data?

there are three columns used in the pie chart. the sum of each column is converted to percentage and then shown in the chart.
i have tried to create one chart as attached with this post, but the result is not what is want.



What does one of the rows look like as a json document.
