Top subgraphs/connectors by traffic/health for a graph over a time window, as compact CSV (header row + one row per subgraph per day). Columns: start timestamp, end exclusive timestamp, fetch service name, fetch count, fetch latency p50 ms, fetch latency p99 ms, fetch with errors count. Ranked by `orderBy` descending: default FETCH_COUNT (busiest); use FETCH_WITH_ERRORS_COUNT for most error-prone, FETCH_LATENCY_P99_MS for slowest. Rows are per-DAY buckets, so for a multi-day window sum a column per subgraph to get the window total. `variantName` optionally scopes to one or more variants (omit for all). `subgraphName` optionally scopes to one or more subgraphs by exact name (omit for all); pattern/substring matching is not supported. Note: `to` must be at least 1 day in the past (DAY resolution).
