The Met Eireann rain radar is shit.
I could be polite about it and say things like “it is so close but it could have been a little better” but that would not be truthful because it is neither usable nor useful.
I remade the rain radar the way it should have been made in the first place.
Packed Circle Chart Builder
One of my work colleagues asked me if I could make something to build Packed Circle Charts and this is what I came up with.
It renders the chart on a <canvas> element and does not have the ability to save the chart in any way whatsoever.
If you make a chart and you want to keep it you will have to grab the screen.
Perhaps, at some point in the future, I will build in the ability to save charts in SVG format but for now I have no plans to do so.
