What are Dash Callbacks?

Can you explain what Dash callbacks are?

Sure! Dash callbacks are functions that allow you to update your Dash app's components dynamically based on user input.

How do they work in a Dash application?

They work by linking input components to output components. When an input changes, the callback function is triggered to update the output.

Can you give me an example of a simple callback?

Absolutely! For instance, if you have a dropdown and a graph, you can create a callback that updates the graph based on the selected dropdown value.

What if I want to have multiple inputs for one output?

You can do that too! Just define multiple input components in your callback decorator, and the function will receive their values.
