+    Function to fast render a chart with multiple panes. This function manipulates graphical
+    output or interfaces with an external framework to display charts with synchronized
+    scales if required.
 
     Args:
-    panes (List[Pane]): A list of Pane instances to be rendered in the chart.
-    sync (bool): If True, synchronize scales of all panes. Default is False.
-    title (str): Title of the chart. Default is an empty string.

+        * panes (List[Pane]): A list of Pane instances to be rendered in the chart. Each Pane
+                            can include various data series and configurations such as OHLCV,
+                            histograms, and indicators positioned on left, right, or middle scales.
+        * sync (bool): If True, synchronize scales of all panes to have the same scale limits.
+                     Default is False.
+        * title (str): Title of the chart. If not specified, defaults to an empty string.
+
+        * size (str): The size designation, which can be 's', 'm', or 'xl'. Defaults to'm'.
+                    Expected values:
+                    - 's' for small
+                    - 'm' for medium
+                    - 'xl' for extra large
 
     Returns:
-    None. This function is expected to manipulate a graphical output or an external framework.
+        None: This function does not return a value. It performs operations to render graphical content.
