Hi Peter.
Spiral works only without clusterization.
Clusterer library - it is not mine, I only use it.
Spiral feature - it is mine, but I can't integrate it to use with clusterer.
One note:
Do you need this feature? Do you want to use route ability (draw routes from/to placemark).
If you want this feature and don't need to do routes - you can check my other extension Zh OpenStreetMap
joomla.zhuk.cc/index.php/zhosmmap-main
It is on development stage, but lot of features from Zh GoogleMap is implemented, clusterer has ability to build spirals
Today I implementing CSV loading into Zh GoogleMap, but after that I'll come back to develop Zh OpenStreetMap:
- need to add ajax loading placemarks and paths
- add CSV file importing
- infowin panel supports
- and lots of other features
PS OpenStreetMap doesn't require billing account, but Google is implemented (check it's limits to map show). Therefore I'm developing Zh OpenStreetMap and trying to add all features I have in Zh GoogleMap
