Geovisualization Chinese science articles

For the current visualization we use:

• HTML5 for general page layout,
• OpenStreetMap for basic map layer,
•  GeoJSON for target the province borders on representing map,
• CSS3 for visual color and general styling,
• JavaScript for hover effects. 

With existed world map we create layer with GeoJSON encoding China provinces (including Taiwan). Next, we create additional layer with data, associated with country/province from base map layer. Then colorize the chloroplast to get the visual color distribution across the map. Also added labels for basic view and additional hover effect with corresponding province/data on it.
