Code Explanation:

Importing Matplotlib:

import matplotlib.pyplot as plt

This imports Matplotlib's pyplot module, which is used for plotting.

Defining the grid size:

rows, cols = 4, 6

The pattern consists of 4 rows and 6 columns, forming a 4x6 rectangular grid.

Creating a figure:

plt.figure(figsize=(6, 4))

This creates a figure with a 6x4 inch size.

Generating the pattern using nested loops:

for i in range(rows):

    for j in range(cols):

        plt.scatter(j, -i, s=500, c='blue')

The outer loop (i) iterates over the rows.

The inner loop (j) iterates over the columns.

plt.scatter(j, -i, s=500, c='blue') places a blue dot at each (j, -i) coordinate:

j represents the x-coordinate (column index).

-i represents the y-coordinate (negative row index, keeping the origin at the top-left).

s=500 sets the dot size.

c='blue' sets the color to blue.

Setting the plot limits:

plt.xlim(-0.5, cols - 0.5)

plt.ylim(-rows + 0.5, 0.5)

plt.xlim(-0.5, cols - 0.5) ensures that the x-axis starts slightly before 0 and extends to cols - 1.

plt.ylim(-rows + 0.5, 0.5) adjusts the y-axis to properly contain all points.

Hiding the axis and adjusting the aspect ratio:

plt.axis('off')

plt.gca().set_aspect('equal', adjustable='datalim')

plt.axis('off') removes the x and y axes for a cleaner look.

plt.gca().set_aspect('equal', adjustable='datalim') ensures that the spacing between points remains uniform.

Adding a title:

plt.title("Rectangle Pattern Plot", fontsize=14)

Sets the title of the plot to "Rectangle Pattern Plot" with a font size of 14.

Displaying the plot:

plt.show()

Renders and displays the pattern.
