– The data cleaning process is like a treasure hunt, where we dig through the data to find and remove the duplicates and understand the relationship between different columns. ๐ต๏ธโโ๏ธ
– The correlation matrix is like a map, showing us how closely related different data points are. It’s like looking at the stars to navigate our way through the data universe. ๐
– Data analysis is like solving a mystery, where every row and column holds a clue, and it’s our job to uncover the hidden story within the data. ๐
– The journey of data visualization is like painting a masterpiece, using colors and shapes to bring the data to life, creating a beautiful and meaningful picture. ๐จ
