Exercise for creating a component and using a shared component.

Use a flow variable to customize the workflow based on a user selection. Create a component and use a publicly available shared component.



Exercise: ComponentsExecute the workflow below. It filters the data to the northmost country or territory in the data. 1.1) Let's look for the northmost country or region on each continent. Create a Value SelectionConfiguration node to select one of the UN continental regions in the data.1.2) Add a Row Filter node in front of the GroupBy node. Filter the data by the selected continent. 1.3) Encapsulate the nodes into a component. Make sure you add a data output to the component.What is the northmost country in Asia? And in Africa?2.1) Visualize the pace of population increase in the countries in a choropleth world map. Drag&dropthe Choropleth World Map shared component from the KNIME Hub (or the EXAMPLES Server). 2.2) Select the Country/Territory and Change (population) columns in its configuration dialog2.3) Open its interactive view. On which continent are the countries located where the populationincreases the fastest? I couldn't use the World Map obviously, so I attempted toinstead do a multi-step filter, but I think I messed up thefinal step(s) in some way. How would I make this work?
