In this part, we create the “business logic” of our basic app. We would like to retroactively analyze our past spendings and to select transactions, which we need to cut in order to achieve a certain savings level. Under the hood, we will have...
Budget @HOME. Data Visualization
In this part we visualize bank transactions data, aiming to get an idea Types of expenses and there share Savings trends Expenses by months and types Just to understand what do we spend money on, and where is potential for savings.
