我正在开发一个实时可视化演示，想要有所创新。似乎所有的大数据实时演示都是基于 Twitter 或者交通数据。是否还有其他提供免费实时数据的选择？
谢谢。

以下是一些想法：
环境数据集
正如其他评论所述，可以查看weather、forecast（或类似服务）。
太空数据
航班
这里有一些实时航班追踪数据：评估计划是免费的，但有限制。
社交网络
Twitter流API、Facebook实时更新API（如果您已经在社交网络上拥有应用程序）、Foursquare
能源生产
各种能源生产（实时和准实时）数据。
对于这些，您可能需要在页面上找到数据来源，抱歉。
网站流量
Google Analytics实时API（适用于您注册的网站）
货币
还有更多吗？

您考虑过环境数据集吗？
首先，有关流量和水质的准实时数据（例如每小时或15分钟）可在USGS获取。此外，NOAA NCDC 和 APIs提供了大量的天气数据。还有一些浮标数据如何？
看到这篇文章让我想起了很多航班追踪数据，这也可以很有趣地进行可视化。

您可以在www.hooksdata.io找到实时数据源。使用查询语言，您可以指定需要的数据，然后添加Webhook URL，以接收数据或随时拉取数据。
API文档：https://www.hooksdata.io/docs/api/introduction/
可用的数据源及示例：
RSS：
输入：
SELECT * FROM RSS('http://feeds.feedburner.com/TechCrunch/')
Twitter用户时间线:
输入:
SELECT * FROM TwitterUserTimeline('Techstars')
输出：
