One thing that bothers me is that charts/apps like this have to use logarithmic scale due to obvious reasons, but log scale is just not very effective for most people to comprehend on an intuitive level. In the last section each pixel is 1,000,000km, and the first section each pixel represents 1 meter, but experience wise it doesn't make the last section feel that much bigger, and I still have to keep looking at the…
It's worth to do a linear scale miniature of the solar system. At the 1:10^9 scale, it fits well within a farm or a big park, all the planets are at a viable size, and the Sun is not too big.
That could make for a cool park. I imagine you'd have clear line of sight between the planets (either by having a clear path between or by raising them up on monuments), and telescopes setup at each planet in such a way that visitors could look at the other planets without people getting in the way.
The Sun would be 1.5 meters across, the Earth would be 1.2 centimeters across, and the whole thing would be 4.5 km from the Sun to Pluto.
