javascript - Smoothing arcs/plot points in D3.js/GeoJSON/TopoJSON/Shapefile (somewhere along the way) -

-

i've been looking around while answer this, , haven't been able figure out.

  • i'm creating topojson file grid based data (grib files).
  • i can pretty interpolate data down finer resolution grid plot points appear smoother when zoomed out, when zoomed in, it's inevitable see blocky grid points.
  • i've looked simplification, a bit not quite smoothing.
  • i'm using d3 render data.
  • is can done on front end or should/can done in raw topojson data?
  • i don't want able tell it's grid, if zoom in 10,000%.
  • here's example of i'm after:

enter image description here

is can done on front end or should/can done in raw topojson data?

this should done on front end. if smooth data before wrote json file, file needlessly big.
