How to display risk on a spectrum low to high?

If you're ok with using plug-ins there's a nice selection from Vuram in the AppMarket including this example: 

Thanks Stewart, I should have included that detail... trying to avoid using a Plug-in (got to love restrictive InfoSec red tape) you've highlighted what I've been running into - several great gauges, sliders, in the AppMarket.

Ah, ok, so it's not as intuitive but you can add reference lines onto column/bar charts (depends if you want the bar to be vertical/horizontal), have the reference lines as the thresholds you describe and the colour your column/bar red/amber/green as appropriate...that's one suggestion...I'll see if there's anything else a bit more intuitive

Like this...

Something like this with richTextDisplayField works? If so below is something that might help. You can try to write in a more efficient way.

a!localVariables(
  local!value: 77 / 10,
  local!items: (enumerate(10) + 1),
  {
    a!richTextDisplayField(
      marginBelow: "NONE",
      align: "CENTER",
      value: a!forEach(
        items: local!items,
        expression: {
          a!richTextIcon(
            icon: if(
              fv!index <= local!value,
              "circle-large",
              if(
                (fv!index - 0.5) <= local!value,
                "adjust",
                "circle-o-large"
