First I started walking through some of the functions under models and added documentation as I understood more about what they were doing. Then, I started fixing some issues that appear to exist due to some change in the interface for the main bokeh functionality.\r\n\r\nI wanted to go ahead and reference [this commit](https://github.com/rothnic/bokeh/commit/e401932ea09e9130461bc5a3097cd4a3c2fbd51e) to see if there is someone already working in this area, and see if extending it would be of interest.\r\n\r\n### Use Cases\r\nI think there are two major use cases that might be different apps, but overlap somewhat:\r\n* Tableau-like Dashboard creation (create a plot, create another, piece them together with controls)\r\n* Exploratory tool that provides faceting (seems somewhat incompatible with the first use case)\r\n\r\n### Features\r\n* More plot types\r\n* More aesthetics to map columns into (color, size, shape, etc)\r\n* \"Saving\" plots to use in a larger dashboard\r\n* Gracefully handle more columns (big list to scroll through, maybe collapse summary by default)\r\n* Handling multiple data sets (configured to different plots on a dashboard, or combining through simple joins of some kind)"},"comment":{"url":"https://api.github.com/repos/bokeh/bokeh/issues/comments/70090268","html_url":"https://github.com/bokeh/bokeh/issues/1703#issuecomment-70090268","issue_url":"https://api.github.com/repos/bokeh/bokeh/issues/1703","id":70090268,"user":{"login":"rothnic","id":452052,"avatar_url":"https://avatars.githubusercontent.com/u/452052?v=3","gravatar_id":"","url":"https://api.github.com/users/rothnic","html_url":"https://github.com/rothnic","followers_url":"https://api.github.com/users/rothnic/followers","following_url":"https://api.github.com/users/rothnic/following{/other_user}","gists_url":"https://api.github.com/users/rothnic/gists{/gist_id}","starred_url":"https://api.github.com/users/rothnic/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/rothnic/subscriptions","organizations_url":"https://api.github.com/users/rothnic/orgs","repos_url":"https://api.github.com/users/rothnic/repos","events_url":"https://api.github.com/users/rothnic/events{/privacy}","received_events_url":"https://api.github.com/users/rothnic/received_events","type":"User","site_admin":false},"created_at":"2015-01-15T14:11:37Z","updated_at":"2015-01-15T14:11:37Z","body":"@fpliger to answer your question, if I remember correctly that isn't being used. I saw the missing reference to the lowercase \"scatter\", so naively replaced it with charts.Scatter. I'll look more into the newer charts components."}}
