    **usage**:

        {% load_chart "lineWithFocusChart" data_set "div_lineWithFocusChart" %}

    **Arguments**:

        * ``chart_type`` - Give chart type name eg. lineWithFocusChart/pieChart
        * ``series`` - Data set which are going to be plotted in chart.
        * ``container`` - Chart holder in html page.

    **kw_extra settings**::
        * ``x_is_date`` - if enabled the x-axis will be display as date format
        * ``x_axis_format`` - set the x-axis date format, ie. "%d %b %Y"
        * ``tag_script_js`` - if enabled it will add the javascript tag '<script>'
        * ``jquery_on_ready`` - if enabled it will load the javascript only when page is loaded
            this will use jquery library, so make sure to add jquery to the template.
        * ``color_category`` - Define color category (eg. category10, category20, category20c)
        * ``chart_attr`` - Custom chart attributes
