Thank you for making this whoever you are. There is a wonderful video at https://www.youtube.com/watch?v=8FT-oz9aZU4 that visualizes space travel and time dilation in Hail Mary. What I wished I had immediately after watching it was an interactive stellar chart.
You're welcome! I love that channel so much. Their videos and the blog post I link in the about section/citations on the starmap were inspirations for making this.
