Remarks
Repeated requests for the same chart use the same file to reduce load on the server. New requests create new files as needed. Files are not cleaned up automatically. FileImageRender is recommended when charts are complex (expensive to generate) or when you expect a large number of requests for a relatively small number of different charts.
