I'm working on a python presentation and need an explanation and answer to help me learn.

Construct a sparse and a dense matrices of size 1000x1000 and Write a program to implement sparse matrix using the data structure (using adjacency list) and Write a function to visualize the sparse matrix in a graphical format

1. Construct a sparse and a dense matrices of size 1000x1000

2. Identify the data structure to store the given sparse matrices

3. Justify your selection of data structure (use adjacency list data structure)

4. Write a program to implement the data structure

5. Write a function to visualize the sparse matrix in a graphical format
