How to write a web-view module?
---

declare a specific tile in the dash.conf. for example:

---
[tile5]
type=d3js
div_name=webview_test
script=webview_template
---
(this will work for this file, see dash.conf for details)

bottledash will look for a "get_chart(target_div_name)"-methode wich shall
return valid HTML-code (as string!).

the "target_div_name" is the "div_name" you delared in the dash.conf-file.
In our case, "tile5" would be in the css-class "webview_test". You can use
the "target_div_name" for dynamic DOM-Manipulations (like with d3js and jQuery)

If you want to use a python import, please use "importlib" inside the
get_chart-function.

see <https://docs.python.org/3/library/importlib.html> for details

To not try to import your own modules using the regular
python import-keyword! You can however import every regular
python-standard-library using the "import" keyword

"""

import importlib

def get_chart(target_div_name):
    html_string = """
<style type = text/css>

.%s {
    color: red;
}

</style>

<div id = "hello">
    Hello World!
</div>
    """ % target_div_name

    return html_string
