An Observable notebook is composed of several cells, each of which can contain JavaScript code or markdown. There are different types of cells, but they generally include **JavaScript** cells for code and **Markdown** cells for text. This cell is a Markdown cell. You can run or interact with a cell by clicking on it (the highlight color will change to indicate selection) and pressing **Shift-Enter**. If the cell is a **JavaScript** cell, the code will execute, and the results will be displayed immediately. If it's a **Markdown** cell, the text will render as formatted content below the cell.

Feel free to experiment with executing this cell.
