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.

首先使用 Plotly.NET 的安装说明，在脚本或 notebook 环境中制作原型。阅读 Chart2D.fs 中的 Bubble Chart 和 Range chart 示例，然后在顶层 Chart API 中实现带有气泡定位功能的新图表。完成的标准是 API 提供一种比例面积图，通过气泡大小比较值，且不使用刻度。
