how add circle-clipped image glyphs chart, without processing , uploading images manually beforehand? i'm open using other modules. i want end result chart (from nytimes). http://imgur.com/a/nv6ta my current understanding can load images directly urls, not desired outcome. http://bokeh.pydata.org/en/latest/docs/reference/models/glyphs/image_url.html my current understanding can load images directly urls this not correct, there imagergba allows sending images raw rgba data, directly embedded in bokeh document. see, e.g., gallery example: http://bokeh.pydata.org/en/latest/docs/gallery/image_rgba.html so assuming images python list of 2d numpy arrays of rgba data (pre-cropped) images want display, bokeh show them with: p.image_rgba(image=images, x=....) of course, have convert images rgba arrays yourself, , crop them, things may easier or more ready made use-case tool.
