sean@14: How to write a web-view module?
sean@14: ---
sean@14: 
sean@14: declare a specific tile in the dash.conf. for example:
sean@14: 
sean@14: ---
sean@14: [tile5]
sean@14: type=d3js
sean@14: div_name=webview_test
sean@14: script=webview_template
sean@14: ---
sean@14: (this will work for this file, see dash.conf for details)
sean@14: 
sean@14: bottledash will look for a "get_chart(target_div_name)"-methode wich shall
sean@14: return valid HTML-code (as string!).
sean@14: 
sean@14: the "target_div_name" is the "div_name" you delared in the dash.conf-file.
sean@14: In our case, "tile5" would be in the css-class "webview_test". You can use
sean@14: the "target_div_name" for dynamic DOM-Manipulations (like with d3js and jQuery)
sean@14: 
sean@14: If you want to use a python import, please use "importlib" inside the
sean@14: get_chart-function.
sean@14: 
sean@14: see <https://docs.python.org/3/library/importlib.html> for details
sean@14: 
sean@14: To not try to import your own modules using the regular
sean@14: python import-keyword! You can however import every regular
sean@14: python-standard-library using the "import" keyword
sean@14: 
sean@14: """
sean@14: 
sean@14: import importlib
sean@14: 
sean@14: def get_chart(target_div_name):
sean@14:     html_string = """
sean@14: <style type = text/css>
sean@14: 
sean@14: .%s {
sean@14:     color: red;
sean@14: }
sean@14: 
sean@14: </style>
sean@14: 
sean@14: <div id = "hello">
sean@14:     Hello World!
sean@14: </div>
sean@14:     """ % target_div_name
sean@14: 
sean@14:     return html_string
