	Value		int
	Timestamp     time.Time
}
  2. group them by truncating timestamp down to closest ‘hour’, ‘day’, ‘week’, ‘month’

go build
./graph-grouping-exercise test-data/example-transactions-1.json hour

call the executable with path to input data json and interval

or using nix to get dependencies locked in flake.lock

nix develop
go build
./graph-grouping-exercise test-data/example-transactions-1.json hour

or using the GroupTransactions function directly from code
