Using KNIME base nodes (not extensions) to create a simple waterfall chart

Hi, I’m new to KNIME but very familiar with building waterfall charts in Excel to visualise the step movements up and down from a start point to and end point. Say for example, the first bar on the left of the chart would say “start value” = 100 then there are n number of steps (let’s say 3) such that step 1 is +10 step 2 is +20 and step 3 is -15. This would result in an “end value” total bar on the right of 115.

I couldn’t see any waterfall chart nodes and can only use the base nodes for now (not extensions) due to IT admin permissions on my work computer. Once I’ve prototyped the concept above I can look to embedding the software in the future, but need waterfalls as part of my sales pitch demo first - as we use them a lot currently.

Thanks
