// You can use the GetMetricWidgetImage API to retrieve a snapshot graph of one or
// more Amazon CloudWatch metrics as a bitmap image. You can then embed this image
// into your services and products, such as wiki pages, reports, and documents. You
// could also retrieve images regularly, such as every minute, and create your own
// custom live dashboard.
//
// The graph you retrieve can include all CloudWatch metric graph features,
// including metric math and horizontal and vertical annotations.
//
// There is a limit of 20 transactions per second for this API. Each
// GetMetricWidgetImage action has the following limits:
//
//   - As many as 100 metrics in the graph.
//
//   - Up to 100 KB uncompressed payload.
