Load dataset :
CSV JSON
function preprocess(data){
data = data.map(function(d){ d.latitude = d.Lat; d.longitude = d.Lon; d.time_begin = parseDate(d.datetime.split(' ')[0]).getTime()/1000; d.time_end = parseDate(d.datetime.split(' ')[0]).getTime()/1000+3600; d.value = 1; return d; }); dataset = coordsToPolygonId(data, window.geoJson); return dataset;
} Add dataset

Run function on dataset and save return value :

function transformDataset(dataset){
transformedDataset = dataset.filter(d=>d.polygon_id==1); return transformedDataset;
} Apply
