Building an analytics application with a robust data analytics dashboard using Next.js, Cube, and Bizcharts is possible. The tutorial starts by creating a new Cube deployment in Cube Cloud, selecting a database, and setting up the necessary credentials to connect to the public database for testing purposes. It then proceeds to visualize data using the Developer Playground, where users can generate dashboards from various templates for different front-end frameworks and data visualization libraries. Next.js is used to build an analytics dashboard by creating a new application, adding required packages, and setting up environment variables with the Cube API endpoint and token. The code initializes the Cube.js API client and uses it to fetch data on the server-side using the `getServerSideProps` function, which allows for faster loading times, especially in slow network conditions.
