The stars featured in the movie and in this chart (and in the book) are real, and reflect their real-world locations.
The planets around the stars, aside from our own solar system (obviously), are fictional-- both Tau Ceti and 40 Eridani are stars where we're looking for exoplanets, but we don't have strong evidence for either yet.
IIRC at the time the book was written, there was some data suggesting a planet detection around 40 Eridani, but has been ruled out since then.
