# Matplotlib - ( Matplotlib Tutorial )

### Syntax

``````import matplotlib.pyplot as plt

x = [1, 2, 3, 4]
y = [1, 4, 9, 16]

plt.plot(x, y)
plt.show()
``````

### Example

``````import matplotlib.pyplot as plt

x = [1, 2, 3, 4]
y = [1, 4, 9, 16]

plt.plot(x, y)
plt.xlabel('X Label')
plt.ylabel('Y Label')
plt.title('Title')
plt.show()
``````

### Output

A plot is generated with the given data points, and the x-label, y-label, and title are added.

### Explanation

Matplotlib is a data visualization library in Python that allows us to create various types of plots, charts, and graphs. It provides various types of plots such as line plots, scatter plots, bar plots, etc. Matplotlib is widely used in data science and machine learning projects to visualize data.

In the above example, we import the `matplotlib.pyplot` module as `plt`, and we define two lists `x` and `y`. We use the `plt.plot()` function to create a line plot of `x` and `y`. We use the `plt.xlabel()`, `plt.ylabel()`, and `plt.title()` functions to add labels and a title to the plot. Finally, we use `plt.show()` to display the plot.

### Use

Matplotlib is used for visualizing data in various fields such as data science, machine learning, finance, biology, etc. It provides a wide range of visualization tools and options to help us understand and analyze data. We can use Matplotlib to create simple line plots, scatter plots, bar plots, histograms, etc. and even more complex plots like heatmaps, 3D plots, animation, etc.
