4.13.1

Fixes

• Exact zeros in statData. statData().set() and setData() stored { value: 0 } (and { value: '' }) nested as { value: { value: 0 } }, so the region was classified as NaN: grey on choropleth maps, and on proportional-symbol maps with a colour encoding the colour function threw, leaving later symbols unfilled and stopping the dorling layout. A stat object is now detected by its value key rather than a truthy value. Reported and fixed by @aborruso (#191, #192).

Example:

const sd = eurostatmap.map('choropleth').statData()
sd.setData({ A: { value: 0, status: '' }, B: 0, C: { value: 1, status: 'e' } })
sd.get('A') // { value: 0, status: '' }  (was { value: { value: 0, status: '' } })
