Superset（Caravel）是由Airbnb（知名在线房屋短租公司）开源的数据分析与可视化平台（曾用名Caravel、Panoramix），该工具主要特点是可自助分析、自定义仪表盘、分析结果可视化（导出）、用户/角色权限控制，还集成了一个SQL编辑器，可以进行SQL编辑查询等。

Python版本
Superset是在Python2.7和Python3.4下测试的，Airbnb生产环境使用的Python版本是2.7.x，并且Airbnb不打算支持Python2.6。因为Centos7自带的Python是2.7.x版本，所以无需额外安装。可以通过python -V查看Python的版本。
Superset is tested against Python 2.7 and Python 3.4.
Airbnb currently uses 2.7.* in production. We do not plan on supporting Python 2.6.
