Proportional area chart

Description

A Proportional Area Charts are used for comparing proportions (size, quantities, etc.) without the usage of scales. They are therefore only suitable to compare a small set of values, and usually should be combined with text annotations displaying the value [1, 2].

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.

Commencez par créer un prototype dans un environnement de scripting ou de notebook en utilisant les instructions d’installation de Plotly.NET. Lisez les exemples Bubble Chart et Range chart de Chart2D.fs, puis implémentez le nouveau graphique dans l’API Chart de niveau supérieur avec un positionnement des bulles. Le travail est considéré comme terminé lorsque l’API fournit un graphique à aires proportionnelles qui compare les valeurs au moyen de la taille des bulles, sans échelles.
