Choropleth map - interactive view isn't working!

I was trying to run the workflow described here:

I was able to run it but it failed when I tried to open the Interactive view. I then got the following error message:

Anyone have any ideas how to solve this?



Since we published the workflow, Google’s API changed. You can fix this by replacing the code block that loads the Google Javascript API with the following:

// Load Google JavaScript API via jQuery getScript()
	.done(function( script, textStatus ) {
		// Load Google corechart package with drawChart() as callback function
		// google.load('visualization', '1', {packages:['corechart'], callback:drawChart});
    		google.charts.load('46', {packages: ['corechart']});
	.fail(function( jqxhr, settings, exception ) {
		// Inform user about failure
		alert("Loading Google API failed.");

Specifically note the commented out google.load on line 5. The new API call is on the 2 lines just below that.

Sorry for the trouble, we need to update these workflows to reflect the API changes. But this should work in the meantime.


I’m afraid I have tried that solution without success.
I have tried to restart workflow and Knime application as well.

Any other reason why it would fail you think?

Well. Another reset worked after all :slight_smile: Thank you very much!

For visualization drill-down purposes. Is it possible to create Choropleth (or other) maps on Scandinavian countries, also down to county & municipal levels?
