Before jumping into data analysis and visualization let’s not avoid the fact that there are other simpler ways to categorize the data and are used in industry for a long time. One of such tools is excel sheet. Some also call it as spreadsheet. The easy user interface differentiating rows and columns in a tabular way is a great way to categorize the data. It’s also very handy when we just have static values for different entities such as a user detail. Let’s say we want to manage data that consists of username, email id, organization, and position. For every user in a row we will add all the details in columns. And for this type of job, excel or spreadsheet is the best feasible option.
