GeoJson to Topojson conversion.

[Manas Sharma]

Hello,

I have downloaded the districts shapefile of India from the datameet maps repo. I then converted it into GeoJson using ogr2ogr and then into topojson using topojson.

The problem I am facing is that when i try to bind it using D3 to the Mercator projection, the topojson doesn't work while the geojson works. I did try debugging by comparing the original geojson features  and the feature array after the conversion from topojson to geojson feature collection in the code. It has a few features missing from the origninal one. Though I doubt that is the cause of the error.

I am getting the error-

d3.js:7651 Error: <path> attribute d: Expected number, "MNaN,NaNLNaN,NaNL…".

 I suspect this has something to do with projections but am not sure what. Can someone help?

Thanks

Manas,

Can you share the code? Most likely, you're referencing the wrong object property from the array object that is returned by d3.json()
