Getting started with Javis

Javis is different from the previously mentioned options as it is not a plotting library like Plots or Makie. Javis only focuses on creating animations. It uses and re-exports objects from Luxor, a 2D drawing package based in Cairo. Here, we will quickly introduce the package by animating our rotation point. However, be aware that you can do much more with it. Let's learn how to create our animation with Pluto:

1. Create a new Pluto notebook and execute using Javis in the first cell.
2. Add a new cell and run the following code:

   function ground(args...)
       background("white")
       sethue("blue")
   end

The preceding code creates a function that will take the Video object, the object to animate, and the current frame. Javis will give those inputs to all user-defined functions, so it is common to use args... for their arguments. This function calls background to set the background color...
