KNIME Weather Data Inspection and Visualization
This part reads data from Snowflake database and reads IoT data to be read in to KNIME. Data pre-processing to transform DateTime values and aggregate temperature readings. Missingtimestamps are also introduced here. Visualizing seasonality with help of ACF andPACF plot and a basic Line plot to see basictrend in data.
