So late Friday the SAP Lumira twitter handle asks:
I spent most of my time trying to locate Halloween data without taking the time to scrape sites. I found Chicago Halloween stores at the Chicago City data portal and came up with this;

It's now very Halloween festive. I thought of using the SAP Jack-O-Lantern that Timo Elliott shared earlier in the day:

But I struggled getting that into Lumira as a Pictogram. It turns out that you need to convert the file to an SVG file.
So I used http://www.mobilefish.com/services/image2svg/image2svg.php site to convert the .PNG/.JPEG file into SVG

Then I could import the image as a pictogram after converting the file.
Then for fun I can replace jack-o-lanterns in the bar/column charts:

I can share the result using Lumira Cloud:

Hopefully next year more Halloween data will be available.
