Ruby有什么图形包/ API？ [英] What graphing packages/APIs exist for Ruby?
问题描述
我正在研究不同语言的在线图形包，想知道当前最新的图形包有一些值得调查的Ruby。
最低期望功能应该包括Google通过其API 。
推荐的包/ API的主要优点简要说明。
Protovis库的Ruby端口根据protovis网站
Protovis使用自定义数据视图简单的标记，如条和点。与快速变得可视化乏味的低级图形库不同，Protovis通过编码数据的动态属性定义标记，允许继承，缩放和布局以简化构建。
作为Protovis，Rubyvis是免费且开源的，在BSD许可下提供。它本身提供了SVG，可以导出为PNG，JPEG和其他图形格式

I'm doing some research into online graphing packages for different languages and would like to know what current, up-to-date graphing packages there are for Ruby which are worth investigating.
Minimum desired capabilities should include the kind which Google offers through its API.
A brief synopsis of the key benefits of the recommended package / API would be appreciated.
Ruby port of Protovis library According to the protovis site
Protovis composes custom views of data with simple marks such as bars and dots. Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction. As Protovis, Rubyvis is free and open-source, provided under the BSD License. Its delivers SVG natively, which could be exported to PNG, JPEG and others graphics formats
