You will need to import the data first, you can use the data prompter to do this, you will need to select grid or scattered file, select the positions in the file and set the dimensions to 3. Then you hit the describe data tab and fill out the form. Once you save this you will get a file that looks like
file = docs/a.dat points = 4 format = ascii interleaving = record-vector header = lines 0 field = locations structure = 3-vector type = float dependency = positions end You could just modify this as awell, the terms are pretty clear. Then you need to create a new visual program. It shold be import->show positions->image when you execute this you will see some tiny dots. There is not much more that you can do with this until yo define connections, that that is another question. Is the data regular at all?? Does it fall on a grid? Or is it purely point data?
