The GXchart API is a web service that allows users to automatically generate graphs and charts. When a user provides the GXchart API with the data they want visualized, the service will return a URL to an image with the charted data. Data can be passed to the GXchart API either through URL, or using SOAP.
Charts created with GXchart will be deleted from their servers after 10 minutes, so users must save a copy for their later use. Use of GXchart is free, and there are no signup requirements.
