v1.5

New features

• Data normalization (option normalizeByField)
  • data normalization by another attribute field in GeoJSON, to normalize values of chosen field by
  • useful for any dataset that is usually shown in a normalized form, e.g. a population density map
  • normalizeByField expects a string of an attribute field that exists in GeoJSON, in a similar fashion to field

Improvements, fixes

• values are now processed and loaded into an object (features), with all their attributes for later use
• features.finalvalue now contains a processed value to base classification on (finalvalue is either untouched or normalized already)
• added some checks for null, set more defaults in-code (missing fill color in point/size symbols, stroke color in line/width mode)
• debug message updates, code cleanup
• updated readme
• updated screenshot
• examples:
  • all: added banner image to examples' info panels, adjusted their text formatting
  • polygons_c.html: now uses fields population2022 as base and areakm2 as normalization attribute
  • combined.html: line features show river discharge for Yukon and its tributaries now, their tooltips display m³/s and cuft/s values, added feature section highlighting
  • rivers_yukon.geojson dataset: now contains river discharge for Yukon and its tributaries
