Dumbbell plot

Description

Dumbbell plot [1] (also known as Dumbbell chart, Connected dot plot) is great for displaying changes between two points in time, two conditions or differences between two groups.

Example:

Pointers

• Ideally, you start prototyping in a scripting or notebook environment where you can iterate fast. installation instructions can be found here: https://plotly.net/#Installation
• Charts like this that are using baseline trace types to create a new chart type should only be implemented in the top-level Chart API. An example where this is already done is the Range chart that combines a set of differently styled line charts.
• When possible, use #IConvertible for data input, as this allows for strings, number types such as int and float, and DateTime.

Comienza en src/Plotly.NET/ChartAPI/Chart2D.fs, especialmente en la implementación de Chart.Range a la que hace referencia el issue. Prototipa el gráfico en un entorno de scripting o notebook siguiendo las instrucciones de instalación de Plotly.NET y revisa cómo se combinan los gráficos de líneas de referencia. Se considera terminado cuando haya una API de gráficos Dumbbell de alto nivel disponible, con entradas #IConvertible flexibles, que muestre las conexiones entre dos puntos descritas en el issue.
