Hi, The line-layer demo: https://dash-gallery.plotly.host/dash-deck-explorer/line-layer Hows far less data than the equivalent deck.gl demo. https://deck.gl/examples/line-layer/ Yet both load and parse the same data source file: https://raw.githubusercontent.com/visgl/deck.gl-data/master/examples/line/heathrow-flights.json Any ideas on why this is the case? I cannot see any obvious cause in the code. Thanks Darren
