Plot 2 columns from a Dataset on the same plot as lists

Question

I have imported as a csv file and converted to a Dataset. I would now like to plot columns of data (by the column title) as ListPlot. I can do this one column at a time, but cannot combine multiple columns.

data = Import["data.csv"];
header = data[[1]];
rest = data[[2 ;;]];
data = Thread[header -> #] & /@ rest // Map[Association] // Dataset 

where data is the csv file give by

A,B,C,D
1,2,4,5
5,3,2,5
7,3,8,3
9,8,7,2

I can plot one column as a ListPlot or ListLinePlot, but not two on the same plot (see image). If I simply enter a couple of lists then the ListPlot command works fine. I have tried the command below but get an empty plot as the return

ListLinePlot[{data[[;;,"A"]],data[[;;,"B"]]}]

ETA: The spaces I had in my titles were causing confusion, so I have edited the csv file indicated above to avoid this confusion. To apply bbgodfrey's solution you need to reference the labels from the Dataset (copy and paste avoids any hassles).

Answer 1

Plot all columns with

ListLinePlot[Transpose@data]

or selected columns with, for instance,

ListLinePlot[(Transpose@data)[[{1, 3, 4}]]]

or, equivalently,

ListLinePlot[(Transpose@data)[[{"A", "C", "D"}]]]

Answer 2

dataset = SemanticImport["data.csv"]

dataset[Transpose /* ListLinePlot]
