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.

先使用 Plotly.NET 的安裝說明，在腳本或 notebook 環境中製作原型。閱讀 Chart2D.fs 中的 Bubble Chart 和 Range chart 範例，然後在頂層 Chart API 中實作具有氣泡定位功能的新圖表。完成的標準是 API 提供一種比例面積圖，透過氣泡大小比較值，且不使用刻度。
