You can use different panels to visualize the metrics. This guide doesn't go into details of Grafana. You can refer to the [Grafana documentation](https://grafana.com/docs/grafana/latest/) for more information. There is a Bar Gauge panel to visualize the total number of requests from different endpoints. You used the `api_http_request_total` and `api_http_request_error_total` metrics to get the data.
