If you only have in your data you may want to transform them into using only symbology and the useful geometry generator.

Let's see how to you can do this and make your beautiful!

Anyone know of an implementation of Delaunay Triangulation in a ?

I've seen a couple in Common Lisp that I could *probably* try to port over.

Related to the rotating 2n-fold polygons to get rhombus rosettes-thing, here is a picture involving rotating partial rings of polygons to getā€¦wellā€¦something.

It is from about 3 years ago.

Wildfires and thick smoke in the interior along the Dalton Highway.
dynamics (expansion + drainage) and on the North Slope.

Day 3: Polygons

Polygon (legend patches)
The ability to use custom shapes for legends has been available since QGIS 3.14 Pi. This is a simple way to transform your map from something that looks generic into one that is unique (and sometimes more informative).

| Day 3 |

This looks like a point map, but zoom in (way, way in) and you'll see it's actually an super-detailed polygon map.

The topic is deforestation in Brazil, over 2019-2020. A large spatial dataset was available (~50,000 shapes per year), which I integrated into a Power BI dataviz. The "hero" visualisation uses Mapbox's choropleth feature.

The whole dataviz is interactive - filtering or selecting part of any visual cross-filters the others, including re-drawing the map. This is where Power BI + MapBox are so impressive together.

I went with a satellite background layer, to highlight the natural features being impacted. Red was the obvious colour for the fire shapes, which I used for each shape's outline. As you zoom in, you can see the shape fill represents the class of deforestation.

This project was quite technically challenging, but I was quite happy with the end result, and it was of some use to at least one NGO working on this topic.

Interactive dataviz, source code, acknowledgements etc:

Finally caught up to the current day!! šŸ„³

I couldn't decide between these two versions - the data is identical but the layer order, layer alphas and base map colour are a bit different.

This is a pattern with 5-fold made of 20-gons that I made a couple of years ago. If you arenā€™t too distracted by the motion, you might be able to see suggestions of lines approximating a 5-fold rosette...and possibly a few others..that may disappear when you look directly at themšŸ˜

This is something that I tweeted a couple of years ago.

It is a pattern based on regular 28-gons which is extendable to form a translationally of the plane. It contains some rings of 7 , some of 4, as well as other groupings.

My eyes perceive a bit of an illusory twist.

There may also be dots appearing and disappearing.

I think that Iā€™ll post this here for those who havenā€™t seen it.

It involves one of a ā€œclassā€ of patterns made of which can be pretty much split into a snub square tiling and its dual cairo-type tiling

Some more stuff from a pattern of . It is an extension of the pattern shown in the next picture, but I had to start again from the beginning because I could no longer get the small split rings that I had initially used as connectors.

The picture showing the polygon pattern with corresponding chain maille is from my 2020 paper (t.co/Km8a2FBIYC).

Here is the piece of from 2 posts back shown with copies of its polygon pattern. I had a similar (but lighter) picture in the art exhibition at JMM 2021.

A few posts back in this thread, I mentioned a short paper that I had written about my escapades.

Here is a link to the very short video that I had done to elaborate on the stuff described in that paper.
