Expenses Chart with scaling elements depending on the value with fetch

I edited a little bit json file and added few things. Everything is fetching from that file: account balance, total spending in month, percentage difference and all values for every day. Based on fetching data bar in the chart with the biggest value is always max height and all other bars are scaled to that one based on their values so the data can change all the time without affecting. Every bar and label with $ are ::before and ::after elements. Also I added focus states for them.

Any feedback about some easier or more clear way to do that I'll appreciate.
