    so kinda wanted to create animated charts in pythonista except that matplotlib creates static ones and non interactive charts. I was thinking if there's a way to sorta wrap Chartjs (a JavaScript library for cretaing charts) in a webview and set it's background to be clear. i tried doing this but i ran into a problem:
    • setting a clear background webview doesn't seem all that easy, although it seems that it could be done using obj_util (something i am unfamiliar with)

    Any help would be very much appreciated thanks alot

    Update: All right so i have been looking around and found this: https://stackoverflow.com/questions/3646930/how-to-make-a-transparent-uiwebview

    Which i tried implementing as follows ( But for some reason pythonista crashes instead):

    #[webView setBackgroundColor:[UIColor clearColor]];
    
    from objc_util import *
    import ui
    
    UIColor=ObjCClass('UIColor')
    
    class WebViewContainer (ui.View):
        def __init__(self, web_view):
            ui.View.__init__(self)
            self.web_view = web_view
            self.add_subview(web_view)
            _web_view = ObjCInstance(web_view)
            _web_view.setBackgroundColor_(UIColor.clearColor().CGColor())
            _web_view.setOpaque_('NO')
    
    w,h=ui.get_screen_size()
    wv=ui.WebView()
    wv.frame=(0,0,w,h)
    wvo=WebViewContainer(wv)
    view=ui.View()
    view.add_subview(wvo)
    view.present()
