Yes, users can create multiple charts of a single dataset.
The dataset is the main source, whereas charts are just for viewing purposes.
Charts help in scheduling the same dataset in different ways i.e bar graphs, and tables. There may be a case when some columns(i.e Shipment Id, First name, Order count) are represented to any specific user, and some different sets of columns(i.e Shipment Id, First Name, Order details) are represented in the different chart to another set of users of a same dataset.
