Custom Curve Guide:

• Terms in the series are denoted by the letter 'k'.
• To use only odd terms you may use '(2*k)+1'.
• Similarly to use only even terms you may use '(2*k)'.
• The Amplitude in the series is denoted by 'A'.
• To use π you can input 'PI'.
• The Equation to the left shows the form that will be computed.

Upload Path Guide:

• This is used for you to upload your own custom path.
• The path is an array of numbers in a JSON file.
• An example is 'test/drawing.json' in the repo.
