-`EXPLAIN ANALYZE GRAPHICAL` is a command available exclusively in the BendSQL client. It allows you to analyze the performance and execution plan of a SQL query by automatically launching your default browser and presenting an interactive visual representation of the query execution process.
-
-This command is supported only in BendSQL v0.22.2 and above. Before using it, ensure that your BendSQL is properly configured. For setup instructions, see [Configuring BendSQL](#configuring-bendsql).
+Analyzes query performance with an interactive visual representation in your browser. Available exclusively in BendSQL v0.22.2+.
 
 ## Syntax
 
 ```sql
 EXPLAIN ANALYZE GRAPHICAL <statement>
 ```
 
-## Configuring BendSQL
+## Configuration
 
-To enable graphical analysis and automatically open your default browser, add the following section to your BendSQL configuration file `~/.config/bendsql/config.toml`:
+Add to your BendSQL config file `~/.config/bendsql/config.toml`:
 
 ```toml
 [server]
 bind_address = "127.0.0.1"        
 auto_open_browser = true      
 ```
 
-## Examples
-
-You can use `EXPLAIN ANALYZE GRAPHICAL` to analyze the performance of complex queries, such as TPC-H benchmark queries, and understand how each part of the query contributes to overall execution time.
+## Example
 
-Here is an example query that calculates aggregates from the `lineitem` table:
-
-```bash
-eric@(eric-xsmall)/tpch_100> EXPLAIN ANALYZE GRAPHICAL select
-    l_returnflag,
-    l_linestatus,
-    sum(l_quantity) as sum_qty,
-    sum(l_extendedprice) as sum_base_price,
-    sum(l_extendedprice * (1 - l_discount)) as sum_disc_price,
-    sum(l_extendedprice * (1 - l_discount) * (1 + l_tax)) as sum_charge,
-    avg(l_quantity) as avg_qty,
-    avg(l_extendedprice) as avg_price,
-    avg(l_discount) as avg_disc,
-    count(*) as count_order
-from
-    lineitem
-where
-        l_shipdate <= add_days(to_date('1998-12-01'), -90)
-group by
-    l_returnflag,
-    l_linestatus
-order by
-    l_returnflag,
-    l_linestatus;
+```sql
+EXPLAIN ANALYZE GRAPHICAL SELECT l_returnflag, COUNT(*) 
+FROM lineitem 
+WHERE l_shipdate <= '1998-09-01' 
+GROUP BY l_returnflag;
 ```
 
-After running the command, BendSQL outputs a message like:
-
+Output:
 ```bash
 View graphical online: http://127.0.0.1:8080?perf_id=1
-
-1095 rows graphical in 21.762 sec. Processed 0 rows, 0 B (0 row/s, 0 B/s)
 ```
 
-This automatically opens your default browser and shows an interactive graphical view of the query execution plan, including operator runtimes, row counts, and data flow between stages.
