I like how there are a several pre made interactive plot templates that allow you to generate interactive plots in one line of code, but that there is also room for customization beyond that. It's pretty easy to get started with bokeh to make simple yet useful interactive plots and web pages. Review collected by and hosted on G2.com.

I've had some issues getting certain features to work that I've ended up just giving up on. There's a learning curve when trying to make very custom things, without a lot of documentation. It's also difficult to debug and requires learning some javascript, which is useful but increases the learning curve. Review collected by and hosted on G2.com.
