Interactive Dashboards and Data Apps with Plotly and Dash

By: Elias Dabbas

Overview of this book

Plotly's Dash framework is a life-saver for Python developers who want to develop complete data apps and interactive dashboards without JavaScript, but you'll need to have the right guide to make sure you’re getting the most of it. With the help of this book, you'll be able to explore the functionalities of Dash for visualizing data in different ways. Interactive Dashboards and Data Apps with Plotly and Dash will first give you an overview of the Dash ecosystem, its main packages, and the third-party packages crucial for structuring and building different parts of your apps. You'll learn how to create a basic Dash app and add different features to it. Next, you’ll integrate controls such as dropdowns, checkboxes, sliders, date pickers, and more in the app and then link them to charts and other outputs. Depending on the data you are visualizing, you'll also add several types of charts, including scatter plots, line plots, bar charts, histograms, and maps, as well as explore the options available for customizing them. By the end of this book, you'll have developed the skills you need to create and deploy an interactive dashboard, handle complexities and code refactoring, and understand the process of improving your application.

Restructuring your app to cater to multiple layouts

At this stage, we haven't moved from the basic structure that we discussed in Chapter 1, Overview of the Dash Ecosystem, and as a reminder, Figure 11.3 shows a simplified representation of the current structure:

Everything will remain the same, with the exception of the layout part. Right now, we only have one layout attribute, and everything was added to the main div. We used tabs to efficiently utilize space in some cases, and from Dash Bootstrap Components we used the Row and Col components to flexibly manage how components are displayed. To create the new layout structure, we need to create one main layout, which will serve as the skeleton of our app. In this layout, we will have an empty div, which will get populated with the appropriate content, depending on the URL we are on. Figure 11.4 shows how this skeleton might look. This is just to make...
