I love the idea of this: that there is a place you could go to get a pulse on the opinions of technology professionals regarding the tools they're working with.
So I apologize for the negativity that follows; it's a cool idea, and you've put work into it and made it look very pretty. That being said: unfortunately, without it being backed up by _data_, this is just one person's opinion and ultimately not very worthwhile as is.
Furthermore the presentation of the data along a single axis 'adoption' (or sometimes 'expectation') is even more confusing. Technology comparisons are not helpful plotted on a single variable as the comparator. It also leads to some very bizzare plots where somehow 'mariadb' has more 'adoption' than 'mysql' or 'postgres'
It's nice, except how they are plugging their own GoCD as a Jenkins replacement. Yes, pipeline builds are nice. But only if you fit their very specific niche, and that's not all that Jenkins does. The GoCD plugin ecosystem is also basically non-existent, the integrations with github/gitlab/etc are all maintained by one guy who refuses to implement bitbucket support even though the GoCD plugins page lists it as the bitbucket plugin.
That's just the first thing I ran into with this radar and it's annoyed me ever since.
I would trust the ThoughtWorks Radar over this but it's nice to see a competitor and a different angle. The market has room for more providers of this kind of information, it just has to be higher quality.
Unfortunately, since the author doesn't really seem to understand the technologies he's trying to plot (GraphQL is listed as a database? really?), and since he doesn't present any data to back up his assertions, I feel that any (professional) negativity towards this post is fairly justified.
Maybe this is the result of someone (junior?) trying to get a grasp of the overwhelming plethora of development tools by documenting his/her current findings and beliefs in a visualization as a help to decide what tool to look into in more detail.
