Expenses Chart Component

The tooltips were a challenge. I first tried to do it with them as a child of the bar. But this did not work since I was adding a opacity to the bar when hovered which made the tooltip have the opacity as well. I managed to get them working by creating a container for the bar and when that container is hovered they appear. Using a visibility: visible to be able to have a fade effect with transition. I made the active bar the current day of the week which at the time of writing the is Saturday.
