Adding Interactivity Using Callbacks
00:00 Add interactivity to your Dash apps.
00:04 In this section of the course, you’ll learn how to add interactive elements to your dashboard. Dash’s interactivity is based on a reactive programming paradigm.
00:14 This means that you can link components with elements of your app that you want to update. If a user interacts with an input component such as a dropdown or a range slider, then the output, such as a chart, will react automatically to the changes in the input.
00:32 This new version of your dashboard will ultimately allow the user to interact with the following filters: region, type of avocado, and date range. However, to create this interactivity involves a number of steps, so to simplify the transition, just one filter will be created initially: the region.
00:52 This will demonstrate the elements that are needed to use Dash’s interactivity. Now let’s make your dashboard interactive.
