Summary  
This chapter demonstrates how to implement an async page component that awaits fetched data, passes it as props to child components, and uses array mapping with conditional rendering to build a dynamic chart UI.  

General domain of usage  
Dashboard data visualization

Let's focus on the dashboard page now and see the theory in action to understand the concept better.

## Back to the Project
Copy and paste the code below into `app/dashboard/page.tsx`. Take a moment to explore the UI, but note that no data is present, so the live page will not show any changes.

 ### Retrieving Data for IncomeChart
To fetch income data, import the `fetchIncome` function from the `'@/app/lib/data'` module and call it inside the `Page` component. Then, uncomment the `IncomeChart` component and check the live page.


Next, follow these steps to view the income chart:
1. Visit the `app/ui/dashboard/income-chart.tsx` file.
2. Uncomment the ready UI code.

This results in the following income chart on the live page.

Learn to build modern, high-performance web applications using Next.js. Set up projects with structured layouts, styling, and routing for seamless navigation. Fetch and display data efficiently while optimizing rendering and performance. Implement advanced features like pagination, CRUD operations, and global search for dynamic web apps. Deploy your Next.js projects and connect them with databases, and add authentication to protect user data.

Let's discuss what you need to learn before diving into the Next.js framework, what to expect from this course, and what you'll build.

We will set up the project, inspect ways to add styling to our app and cover visual aspects such as images, fonts, pages, and layouts.

Learn how to easily create and manage a new view for your app and navigate through all pages seamlessly with an incorporated routing system.

Deploy the Next.js app using GitHub and Vercel accounts. Additionally, establish a database to supply the app with the necessary data.

Consider how to obtain and show data to the user clearly and efficiently.
