• A.* In your application, create a metric with a metricKind set to DELTA and a valueType set to DOUBLE.
  * In Stackdriver's Metrics Explorer, use a Slacked Bar graph to visualize the metric.
• B.* In your application, create a metric with a metricKind set to CUMULATIVE and a valueType set to DOUBLE.
  * In Stackdriver's Metrics Explorer, use a Line graph to visualize the metric.
• C.* In your application, create a metric with a metricKind set to gauge and a valueType set to distribution.
  * In Stackdriver's Metrics Explorer, use a Heatmap graph to visualize the metric.
• D.* In your application, create a metric with a metricKind. set toMETRlc_KIND_UNSPECIFIEDanda valueType set to INT64.
  * In Stackdriver's Metrics Explorer, use a Stacked Area graph to visualize the metric.
