| /** |
| * ONOS GUI -- SVG -- GeoData Service |
| * |
| * The GeoData Service facilitates the fetching and caching of TopoJSON data |
| * from the server, as well as providing a way of creating a path generator |
| * for that data, to be used to render the map in an SVG layer. |
| * |
| * A TopoData object can be fetched by ID. IDs that start with an asterisk |
| * identify maps bundled with the GUI. IDs that do not start with an |
| * asterisk are assumed to be URLs to externally provided data. |
| * |
| * var topodata = GeoDataService.fetchTopoData('*continental-us'); |
| * |
| * The path generator can then be created for that data-set: |
| * |
| * var gen = GeoDataService.createPathGenerator(topodata, opts); |
| * |
| * opts is an optional argument that allows the override of default settings: |
| * { |
| * objectTag: 'states', |
| * projection: d3.geo.mercator(), |
| * logicalSize: 1000, |
| * mapFillScale: .95 |
| * }; |
| * |
| * The returned object (gen) comprises transformed data (TopoJSON -> GeoJSON), |
| * the D3 path generator function, and the settings used ... |
| * |
| * { |
| * geodata: { ... }, |
| * pathgen: function (...) { ... }, |
| * settings: { ... } |
| * } |
