+The power of Fused Workbench is the ability to easily edit your code and it executes instantly without you having to hit "Run".
+The UDF editor calls [`fused.run(udf)`](/python-sdk/top-level-functions/#run) under the hood for you upon updates to the code.

 Let's give it a try, replace the default UDF with this code into the UDF Builder to render subway stations on a map:

 Now you can dive deeper into more advanced topics:
 - Learn more about [UDFs](/core-concepts/why/) (We showed how to return static vector files, but we can do a lot more!)
 - Take a deeper look at [Workbench](/workbench/overview/)
