+title: EXPLAIN ANALYZE GRAPHICAL
+---
+
+`EXPLAIN ANALYZE GRAPHICAL` used to open a browser page to display a query execution plan along with actual run-time performance statistics.
+
+This is useful for analyzing query performance and identifying bottlenecks in a query.
+
+ **Note:** This feature is available only in `bensql`.
+
+## Syntax
+
+```sql
+EXPLAIN ANALYZE GRAPHICAL <statement>
+```
+
+## Examples
+
+TPC-H Q21:
+```sql
+EXPLAIN ANALYZE GRAPHICAL SELECT s_name,
+    ->        Count(*) AS numwait
+    -> FROM   supplier,
+    ->        lineitem l1,
+    ->        orders,
+    ->        nation
+    -> WHERE  s_suppkey = l1.l_suppkey
+    ->        AND o_orderkey = l1.l_orderkey
+    ->        AND o_orderstatus = 'F'
+    ->        AND l1.l_receiptdate > l1.l_commitdate
+    ->        AND EXISTS (SELECT *
