As an AI language model, I don't have the context to provide a detailed explanation for this code. However, I can provide you with some basic information.
This line of code is used to create a new figure object in Matplotlib. The "Figure" class is a top-level container for all plot elements, which includes Axes, titles, legends, and other components.
The parameters passed to the constructor are:
- `width`: the width of the figure in inches.
- `height`: the height of the figure in inches.
- `dpi`: the resolution of the figure in dots per inch.
For example, if you set `width=6`, `height=4`, and `dpi=100`, the resulting figure will be 600 pixels wide (6 inches * 100 dpi) and 400 pixels tall (4 inches * 100 dpi).
Once the figure object is created, you can add one or more Axes objects to it using the `add_subplot()` method.
