Implement Scatter Plot Matrix

[edciriac]

Scatter plot matrix should be added to available visualizations. There is two possibilities of implementing the component:

1. Make a single component using ECharts grids. Use grids to make the matrix and assign a scatter plot for each grid.
2. Make a component for a single scatter plot and a parent component which then contains a grid using HTML divs/tables or any other HTML way and add a single scatter plot component to each div/cell in the table.

Here's an ECharts example of the scatter plot matrix in one echarts instance: Scatter plot matrix
