I've never seen these charts, but I like them much more than the video screenshot you posted. These SparkRadar charts seems to do a good job of plotting the relevant parts of a radar chart in a single chart, while the alternative requires a video. The key trick is replacing location with distance, which is generally what we care about. Basically, is a storm nearby? and is it coming closer? are much more important that asking which direction the storm is coming from.

You also mentioned that the New York includes something "far away in both time and space", but your alternative Baltimore chart actually includes the weather over Ottawa, Canada over 500 miles away!

Most importantly, there are challenges with viewing and interpreting video charts. Even here, you've posted a screenshot of the video without a link to the video itself. Thus, the reader is forced to look at location as the two dimensions, with no sense of time. Similarly, these are hard to include in reports and presentations. Even when they work, I don't like needing to watch N loops of a video trying to piece together the key information I need: how far is the storm from me and how does the distance change over time.

I agree with Brian. What I want to know is how close the storm is and when I need to worry about getting wet. Flipping the time axis would be helpful - I'm used to seeing time from top to bottom on schedule charts, for example, rather than left to right.

Yeah, I have to say that I find these intriguing.

They are somewhat disorienting at first, but not terribly complicated to understand.

They desperately need some more finesse in the design choices.

I think it's clear that I can get more information at a glance from the spark radar than I can the map, but I can obviously get a more complete understanding by watching the animated map.

Neither display fills the role of the other, and I think at the very least there is room for both methods of looking at this information.

Either way, they're an interesting concept.

"Firstly, the axes are unnatural. Time runs vertically, defying the horizontal convention."

I use my scheduling calendar in outlook with a vertical axis every day and I don't find it unnatural.

What I find lacking in the spark radar is the ability to tell if the storm is actually going to reach my location or just get close and then pass on one side or the other.

The second challenge is that storms move from west to east (in my geographical location). It would have taken me less time to understand this chart if the horizontal axis had been reversed.

As jlbriggs noted, more finesse in the design choices is also needed. But overall this is innovative and should not be dismissed as merely "art".
