"Smart mapping" approaches #49

Open zhiyuli opened 4 years ago

zhiyuli commented 4 years ago

This issue is to improve the Choropleth Maps visualization. Any color ramp needs a set of matching breaks on values of attributes.

Option 1: ESRI has "smart mapping api" -- but may need data and layer in certain format

Option 2: use other backend libs to do statistical analysis in the preprocessing phase to get breaks for all possible visualization attributes. Send to frontend in JSON https://github.com/pysal/mapclassify/blob/master/notebooks/plot.ipynb https://github.com/pysal/mapclassify https://pysal.org/mapclassify/ https://nbviewer.jupyter.org/github/pysal/mapclassify/blob/master/notebooks/south.ipynb

Option 3: find a frontend equivalent lib to do the statistical analysis on breaks
