i considered using typed arrays for the input data, but most data is gonna come from JSON parsing, which will automatically allocate at least the size of a non-typed array, so i used that as the lowest common denominator for the demos. my point was more that many charting libs use record-based datasets like [[a,b],[c,d]] which would need to allocate possibly hundreds of thousands of arrays or objects. uPlot uses something closer to a column store for its data format, which saves a lot of mem, in addition to not duplicating the same timestamps for every series.
