DatMelt includes EGADS library that can be called from any Java script. The library includes a collection of time-series and anomaly detection models that are applicable to a wide-range of use cases.
Here is a simple example that downloads a configuration file and a CVS data. Then it runs an algorithm give in the configuration file. One can also customize the type of output:
The code produces a GUI image with the original time series data and with anomaly detected features.
