如何将DiagrammeR甘特图保存为svg文件

我想知道如何将使用DiagrammeR的mermaid函数生成的甘特图保存为SVG文件

以本文中的甘特图为例：

如何将此图表导出到svg文件中

我已经看到有一个工具可以将DiagrammeR grViz图形导出为svg格式（），但是这个工具不适用于mermaid甘特图

如果尝试将其应用于上一个甘特图，则会出现以下特定错误：

Error in context_eval(join(src), private$context) : 
Error: syntax error in line 2 near 'gantt'

有没有任何方法可以修改这个工具，使它可以处理美人鱼图形呢
