Task 2: Create a BIRT Report1. Execute the provided workflow. It aggregates and visualizes population and travel riskinformation on the different continents. 2. Send the output of the top branch, the pivot table, to BIRT for use in a report3. Send the bar chart to BIRT4. In the BIRT Report editor, use a grid to layout the following elements:- A report title- A pivot table- A bar chart Task 1: Write Data to a FileRead the JoinedCountryTable.table file by executing the Table Reader node. This table containsinformation about the demographics, geolocation, and travel risks in the different countries/territories in 2020.1. Filter the data to the countries/territories in the travel risk category 1 (Exercise normalprecautions)2. Filter these data to countries/territories with a maximum one million inhabitants in 20193. Write the filtered data into a “SmallSafeCountries.csv” file in the data folder. Overwrite the file if italready exists. I'm struggling to understand how to usepivot. I am really not sure what I did here, Iwas lucky it would even execute because Ikept trying different things and it would getstuck executing. Since the column fall onlyhas 2 options, found and fell, I wanted tosee the geolocation of the found onesassociated with its ID. That is what I wastrying to do but I don't think I wassuccessful ?
