How to structure my table for both stacked area chart and pivot table?

I understand that you should structure your table so that all values of the same type should be in one column. But I still want to create a stacked-area chart with the columns as my series.

For example, see the following two tables:

Table1:

Year	Bears	Dolphins	Whales
2017	8	150	80
2018	54	77	54
2019	93	32	100
2020	116	11	76
2021	137	6	93
2022	184	1	72

Table2:

Year	Animal	Amount
2017	Bears	8
2017	Dolphins	150
2017	Whales	80
2018	Bears	54
2018	Dolphins	77
2018	Whales	54
2019	Bears	93
2019	Dolphins	32
2019	Whales	100
2020	Bears	116
2020	Dolphins	11
2020	Whales	76
2021	Bears	137
2021	Dolphins	6
2021	Whales	93
2022	Bears	184
2022	Dolphins	1
2022	Whales	72

Which is correct? If Table1, how do I create a PivotTable with the data? If Table2, how do I make a stacked area chart?

That’s amazing. You’re a genius. Thank you so much!
