Ideas

• use session store for input buffer (vs. recalculating trace each time)
• simple moving average (Math.mean)
• kalman filtering (kalmanjs)
• generate new trace (add/extend) for filtered data on plot

As mentioned on the dash plotly forums, clientside callbacks for downloading figure data will fail in the current Edge browser release.

The root cause for this is that the JS-based CSV generation (assets/app-download.js) is currently implemented through the FileAPI. EdgeHTML v18 doesn't support the File constructor...

From assets/app-download.js#L64:

        // generate file and send through file-saver
        const file = new File([dataTable.concat("\n\n", footer)], "bpi.csv", {
            type: "text/csv;charset=utf-8"
        });

Solution:
The Blob object is fully supported in most current browsers.

• Migrate from using FileAPI's File constructor to the Blob constructor.
• Need to research FileSaverJS API on how to name the file contents.
