For your use case, there's a much simpler solution. Mapshaper already has support for applying different amounts of simplification to different features in a layer, using the `variable` flag in...

The coordinates of this sample dataset describe a collapsed shape with area 0, which gets converted to a null shape on import. Many of mapshaper's commands currently will fail ungracefully...

That's not quite enough info to help me debug this. To help me troubleshoot this problem, you could tell me what browser and OS you're using, whether there are any...

Thanks for the tip, Thomas, you may have identified the problem. I'll try to add a useful error message if someone tries to import a ".json" (or .geojson, etc) file...

@Ideenpionier I wasn't able to replicate the problem with the file that you provided... did you try to download the file from the URL you posted using a tool like...

I'd like to add this feature. One option would be to decompose non-topological polygons into topological data in a way that preserves all of the original spatial information, so you...

This issue is related to the question of how to process files that are inconsistent or heterogeneous in some way. In this case, some of your files contain polyline features...

Hi, can you send some sample data that exhibits this behavior, to help me debug it? You could drop the file in a comment here or email it to me...

I think this feature would be simple to add... one way would be to add an option to the output command, say, `svg-data=` or `attribute-data=`, followed by a list of...

Before we write any new code, I have a couple of questions. For storing ordinary data values in SVG elements, there's the 'data-*' naming convention, which looks to be part...
