First line of the file should have a header which indicates the names of columns (your features).

)DateTime
: date time values (e.g."1997-07-16"
,"1997-07-16T19:20+01:00"
)
Once your data is loaded, this information is shown in the bottom part of the Datasets
tab, where each column is assigned an index in order of appearance in the first line of your CSV file along with their inferred data type.
