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.

Learning about the different ways of using scatter plots: markers, lines, and text

We have a number of different options when using graph_objects to create scatter plots, as mentioned in the introduction, so we will be exploring it together with Plotly Express. To give you an idea of the versatility of the available scatter plots, the following code extracts all the scatter methods available to the Figure object, as well as those available in Plotly Express:

import plotly.graph_objects as go
import plotly.express as px
fig = go.Figure()
[f for f in dir(fig) if 'scatter' in f]
['add_scatter',
 'add_scatter3d',
 'add_scattercarpet',
 'add_scattergeo',
 'add_scattergl',
 'add_scattermapbox',
 'add_scatterpolar',
 'add_scatterpolargl',
 'add_scatterternary']
[f for f in dir(px) if 'scatter' in f]
['scatter',
 'scatter_3d',
 'scatter_geo',
