Effective data visualization can be considered a form of Data storytelling.

Here's why:

1. Data encryption is the process of converting data into a code to prevent unauthorized access. This doesn't have much to do with visualization.

2. Data compression is the process of reducing the size of a data file, which also doesn't relate to visualization.

3. Data storytelling, on the other hand, involves presenting data in a way that tells a story. This is often done through data visualization, where complex data is presented in a graphical or pictorial format that's easy to understand and interpret.

4. Data manipulation involves changing data to make it easier to read or process, which is not the primary goal of data visualization. While data visualization can involve some data manipulation (like cleaning up the data to prepare it for visualization), the main goal is to present the data in a way that tells a story, not just to change or manipulate the data.
