Pareto chart implementation (#431)
* Initial implementation for Pareto chart Co-authored-by: John Casagranda <[email protected]> Co-authored-by: Gauthier Segay <[email protected]> * missing files Co-authored-by: John Casagranda <[email protected]> Co-authored-by: Gauthier Segay <[email protected]> * C# has the fun too. Co-authored-by: John Casagranda <[email protected]> Co-authored-by: Gauthier Segay <[email protected]> * Confused... Co-authored-by: John Casagranda <[email protected]> Co-authored-by: Gauthier Segay <[email protected]> * Typo... Co-authored-by: John Casagranda <[email protected]> Co-authored-by: Gauthier Segay <[email protected]> * Adjustments: remove the points chart, using the markers on the line chart instead, adding overloads to take the labels and values separately, adding ShowGrid as an option.

*Summary:* This example shows how to create a Pareto chart in F#.

A Pareto chart is a type of chart that contains both bars and a line graph, where individual values are represented in descending order by bars, and the cumulative total is represented by the line.
57+
The chart is named for the Pareto principle, which, in turn, derives its name from Vilfredo Pareto, a noted Italian economist. <sup>[Source](https://en.wikipedia.org/wiki/Pareto_chart)</sup>
