Plugin Geomap: Suggest combining OpenLayer configuration with data

[bsouster]

Hey @shawnthompson @jvanulde
The plugin is currently using the data-wb-geomap attribute to set the configuration of the map, separate from the data table(s).

I'm thinking it might be better to combine the configuration with data tables. It would be easier to read, identify relationships and much easier to write.

Consider formatting a legend item / set of table data in JSON

    "field": "Rank",
    "value": [3],
    "filter": "GREATER_THAN",
    "init": {
        "fillColor": "#e74c3c",
        "pointRadius": 2.6,
        "fillOpacity": 1.0,
        "strokeWidth": 8,
        "strokeColor": [ 231, 76, 60, 0.5 ]

And instead writing it into the data table

<table  data-wb-geomap='"id":"cities"'>
    <tr>
        <th data-wb-geomap='{ "label":"Label for legend", "fillColor":"#e74c3c", "pointRadius": 2.6, [etc] }'>Rank</th>
        <th>Census subdivision</th>
        <th>Population 2011</th>
    </tr>

See WET's charts and graphs for a working example of this approach:

The only problem with this approach is that users would need to implement two different styling mechanisms, one for tabular data and one for external file-based data. Twice as much documentation would be required.

BTW - Geomap will be moving to a pure CSS styling solution in the future.
