Apache Superset Quick Start Guide

By: Shashank Shekhar

Overview of this book

Apache Superset is a modern, open source, enterprise-ready business intelligence (BI) web application. With the help of this book, you will see how Superset integrates with popular databases like Postgres, Google BigQuery, Snowflake, and MySQL. You will learn to create real time data visualizations and dashboards on modern web browsers for your organization using Superset. First, we look at the fundamentals of Superset, and then get it up and running. You'll go through the requisite installation, configuration, and deployment. Then, we will discuss different columnar data types, analytics, and the visualizations available. You'll also see the security tools available to the administrator to keep your data safe. You will learn how to visualize relationships as graphs instead of coordinates on plain orthogonal axes. This will help you when you upload your own entity relationship dataset and analyze the dataset in new, different ways. You will also see how to analyze geographical regions by working with location data. Finally, we cover a set of tutorials on dashboard designs frequently used by analysts, business intelligence professionals, and developers.

Customizing the visualization

The Ethereum dataset has a Date (UTC) column, a UnixTimestamp column, and a value representing the total transaction volume in USD on that date. Let's chart the Value column in the latest Ethereum transaction history data:

Data form for the Ethereum transaction volume chart

The Data form calculates the sum of transactions grouped by dates. There is only one value over which the SUM(Value) aggregate function is computed:

Table chart with total value of Ethereum over the years

The sum of transaction values, grouped by the Date column value and sorted in descending order, shows that the busiest days in the Ethereum network are also the most recent.
