 # OUTPUT
 
 1. Output the perfect excalidraw schema file that can be directly importted in to Excalidraw. This should have no preamble or follow-on text that breaks the format. It should be pure Excalidraw schema JSON.
+2. Ensure all components are high contrast on a white background, and that you include all the arrows and appropriate relationship components that preserve the meaning of the original input.
+3. Do not output the first  and last lines of the schema, , e.g., json and backticks and then ending backticks. as this is automatically added by Excalidraw when importing.
