 ## Integration with Makie Utilities
 
 This example showcases the seamless integration of the Smith chart with Makie.jl's interactive functionalities. It demonstrates a typical scenario used to teach impedance matching, where we aim to transform a source impedance of 50+100j $\Omega$ to a load impedance of 50 $\Omega$. To achieve this, we utilize a transmission line and a parallel stub, and control their lengths via sliders. By dynamically adjusting these lengths, users can observe how the source impedance seen by the load evolves on the Smith chart, visually illustrating the impedance matching process.

 You can also draw reflection data with the `reflection = true` keyword. This is useful, for example, when you want to visualize the S-parameters of a simulation or measurement.
