我正在使用带有 Shiny R 的 Google Motion Chart，但我无法编辑一些基本内容。我是 Shiny R 的新手，已经开始喜欢它了。这是我的代码：

shinyUI((
mainPanel(

htmlOutput("view_gviz")

现在，这里列出了我不能做的事情：
- 我确实想放置/编辑工具提示。我在Gapminder 网站上看到过一个例子。我想在 X 轴、Y 轴、颜色和大小的指标上添加工具提示。
- 删除播放按钮和播放速度按钮。这听起来不是一个好主意，但我确实想拖动滑块并且随着时间的推移没有动画。使用完整的数据是有意义的。
- 放大不适用于鼠标单击。我们必须用键盘按回车键才能缩放。我们有任何解决方法来解决这个问题吗？
