It has to be the way the function ExsmpleData has been created by Wolfram. Most likely, ExampleData calls Import. Note, I do not know this to be fact. But since people who are employed by Wolfram have previously stated large portions of Mathematica are written using Mathematica code, this would seem to be a reasonable conclusion. >Also, how does Mathematica know which variables to use in the plot? I doubt Mathematica does know which variable to use. But the person who created the example undoubtedly knew what was in the file. And if he did not know what was in the file, he could have used the command ExampleData to see what was in the file. Look at the help page for ExampleData
