Hi! I’ve included a link to my constellation mapping project on Github.

    "In this project you are Dr. Jillian Bellovary, a real-life astronomer for the Hayden Planetarium at the American Museum of Natural History. As an astronomer, part of your job is to study the stars. You've recently become interested in the constellation Orion, a collection of stars that appear in our night sky and form the shape of [Orion](https://en.wikipedia.org/wiki/Orion_(constellation)), a warrior God from ancient Greek mythology. \n",
    "\n",
    "As a researcher on the Hayden Planetarium team, you are in charge of visualizing the Orion constellation in 3D using the Matplotlib function `.scatter()`. To learn more about the `.scatter()` you can see the Matplotlib documentation [here](https://matplotlib.org/api/_as_gen/matplotlib.pyplot.scatter.html). \n",
    "\n",
    "You will create a rotate-able visualization of the position of the Orion's stars and get a better sense of their actual positions. To achieve this, you will be mapping real data from outer space that maps the position of the stars in the sky\n",
    "\n",
    "The goal of the project is to understand spatial perspective. Once you visualize Orion in both 2D and 3D, you will be able to see the difference in the constellation shape humans see from earth versus the actual position of the stars that make up this constellation. \n",

I’m just getting started with Python and its libraries, so I didn’t do anything too fancy, but getting the 3d plot to work in the end was pretty cool and has me excited to learn more.

Thanks for your feedback!

Hi @sjanaep.

Congratulation on getting your plots created. I’d never knock a good scatter plot.

A bit of feedback: Have a look at the the locations of your 3D points relative to the z-axis. I think they’re all sitting on the x-y plane where z=0. See this reply for a little detail on that and how to fix it- Orion Constellation Project: What's wrong with my z-axis?

As a second point if you’re plotting a graph like this it’s very rare that you’d not include labels for the axes. You’d have to sit and explain the graph to me whereas labels would save us both some time. Get in the habit of adding them now .
