Add parallel coordinate plots

[GoelBiju]

Description:

Support parallel coordinate plots as a plugin in the frontend. An example of drawing parallel co-ordinate plots in D3.js is shown in this example. We can make use of the current DTLZ data for the time being to draw them.

Acceptance criteria:

• Parallel co-ordinate plots can be drawn using D3.js,
• Visualise DTLZ data using parallel coordinate plots.

Going forward @djw213 mentioned it would be ideal to use this to visualise 5-objective data.

As well as the D3.js example, we could try something a bit simpler to get it working i.e. the Parallel Coordinate Plot (PCP) in Plotly.js: https://plotly.com/javascript/parallel-coordinates-plot/. This could be utilised in the same way as the 3D scatter plot on the #61 branch.

If we are to get this working, this offers more features out of the box than having to re-implement the same features with D3.js.
