This repo explores how we make big data - how all the individual data points make up the constellation of our lives.
To add your own points, simply open "postcards.json" and add your points at the top. You can add them by hand with a chunk of geoJSON that'll look like this:
{
"type": "Feature",
"properties": {},
"geometry": {
"type": "Point",
"coordinates": [
-81.650390625,
39.8928799002948
]
}
},
Or you can use tools like geoJson.
