使用 Google Visualization API 时数据是否会发送至 Google？
我正在为客户开发一个网络应用程序，我想使用 Google API 来绘制一些漂亮的图表。
客户拥有一些敏感数据，并提出了一些安全方面的担忧，具体来说，他们不希望自己的数据“流向谷歌”。
有 2 个选项或 API 用于生成图表。图表 API，您可以在其中构建 URL 并提交给 Google，以便它可以生成图形图像 - 显然客户端数据会发送给 Google，因此此选项是不行的。
第二个选项是使用可视化 API。据我所知，生成可视化的代码是从 Google 下载的，但用于构建输出的数据永远不会离开浏览器，因此与敏感数据一起使用是“安全”的。这是准确的描述吗？
我浏览了 Google API 文档来尝试回答我的问题，但似乎找不到明确的答案。
请指教。
I am developing a web app for a client and I want to use the Google API's to draw some nice graphs.
The client has some sensitive data and has raised some concerns about security, specifically, they do not want their data "going to Google".
There are 2 options or API's for generating charts. The Chart API, where you build a URL and submit to Google so that it can generate a graph image - obviously the client data IS going to Google so this option is a no no.
The second option is to use the Visualisation API. As far as I am aware, the code to generate the visualisation is downloaded from Google, but the data used to build the output never leaves the browser, and therefore is "safe" to use with sensitive data. Is this an accurate description?
I have looked through the Google API documentation to try and answer my question but cant seem to find a definitive answer.
Please advise.

我找到了我的问题的答案。对于每种类型的可视化、面积图、折线图、带注释的时间线等，Google 文档中都有一个数据政策部分。对于可视化，我有兴趣使用数据政策部分指出：
看来我只见树木不见森林！
I found the answer to my question. There is a Data Policy section in the Google documentation for each type of visualisation, Area Chart, Line Chart, Annotated Time Line etc. For the visualisations I'm interested in using the Data Policy section states:
Guess I didn't see the wood for the trees!
如果您担心使用谷歌的 API，那么我建议您使用不同的可视化 API。
正如@Rook所说，谷歌记录了一切。
这里的缓解因素是背景。如果您发送的数据没有上下文，那么我不会担心。据他们所知，它可能正在绘制鸡舍扩建图。
但是，如果您的图表确实包含可以追溯到重要内容的上下文数据，那么您需要在本地安装一些东西来为您进行渲染。
If you're worried about using google's API, then I'd suggest you use a different visualization API.
As @Rook said, google logs everything.
The mitigating factor here is context. If the data you are sending has no context, then I wouldn't worry about it. It could be charting chicken house expansions for all they know.
However, if your charts do include contextual data that can be traced to something important, then you'll need to have something installed locally to do the rendering for you.
这里https://developers.google.com/chart/interactive/docs/security_privacy 您可以查看实际条款和条件：
正如你所看到的，这还不清楚。有必要定期审查文档（不仅仅是条款和条件），因为条款和条件很少具体。
Here https://developers.google.com/chart/interactive/docs/security_privacy you can see actual terms and conditions:
As you can see, it's not clear. It's necesary to review documentation periodically (not only terms and conditions), because terms and conditions are few specific.
