# Challenge 1: Fundamentals of Plotting

Matplotlib, a cornerstone visualization library in Python, provides a vast array of plotting capabilities that are both expressive and efficient. Some compelling advantages of using Matplotlib for your data visualization tasks are:

• Versatility: Matplotlib supports a diverse range of plots, from basic line plots to more complex visualizations like contour plots.
• Customization: Every aspect of a plot, from its colors to its labels, can be tailored, providing full control to the user.
• Integration: It works seamlessly with other libraries, especially Pandas and NumPy, making it a fundamental tool in the data analysis workflow.

For budding data scientists, analysts, or anyone keen on visual representation, Matplotlib's plotting functions act as a bridge between raw data and insights.

Plot three foundational graph types using Matplotlib:

1. Plot a simple line graph.
2. Create a scatter plot.
3. Generate a histogram.
Code Description
`plt.plot(x, y)`

The `plt.plot()` function plots y against x as lines. It is commonly used for displaying a series or trajectory in a two-dimensional space.

`plt.scatter(x_scatter, y_scatter)`

The `plt.scatter()` function creates a scatter plot which displays values for two variables for a set of data. The dots in a scatter plot not only report what values occur together, but also show how often they do.

`plt.hist(data, bins=30)`

The `plt.hist()` function computes and draws the histogram of the input data, offering insights into the distribution. The parameter `bins` denotes the number of bins (intervals) to be used for the histogram.

Everything was clear?
