Test Plan for v1.0

High-level list of testable processes:

1. Data processing & Render
2. Tooltips
3. Legend filters
4. Data updates

Quick Ideas of testable items:

All charts:

1. Not providing labels in chart configs (currently throws an exception, ideal behaviour would be to not render the chart an display a console.error)

Non-axis charts (Pie & Donut):

1. Providing multiple datasets for Pie & Donut (shouldn't work, and in fact will break legend filtering, ideal behaviour would be to not render the chart an display a console.error)
