NOTE: this is still pretty experimental work so consider the APIs volatile.
D3 comes from a very prestigious lineage and is arguably one of the most powerful open source visualizations libraries available. This power comes at a cost of having a relatively steep learning curve. The goal of dangle is to minimize this curve as much as possible.
We chose AngularJS because directives allow us to create an HTML based DSL around D3, making it extremely easy to insert (i.e., dangle) graphs from the DOM in a concise, declarative manner. D3's direct DOM manipulation fits well with Angular's DOM based templating. We believe that in order to provide the best experience, we have to be opinionated here.
If you'd like something more framework agnostic then you should have a look at NVD3.
elasticsearch allows you to define different time intervals in your query but the interval is not returned as part of the response, making it difficult to auto-detect the proper interval. We've got a pull request in that resolves this.
the date histogram in elasticsearch is a true histogram meaning that empty bins are not created for missing intervals. This causes issues with the x-axis (time) because we're using D3 time scales which automatically produce the best time labels for the given period. We're working on a possible patch to resolve this in elasticsearch.
