1. You can read in delimited text data using a Data Asset import node. From the Palette, under Import, add a Data Asset node to your flow.
2. Double-click the node to display its properties and select the data file drug1n.csv.
3. Now that you've added the data file, you may want to glance at the values for some of the records. One way to do this is by building a flow that includes a Table node. An easier way is to simply right-click the Data Asset node you just added and select Preview.
