While your mission to propagate an aesthetic factor in Data Viz domain is great, both versions have issues in their current state.
- Vertical text — always bad, never use it.
- 50-pixel legend serifs that
are of no function.
- There are no grid lines for the eye to follow. The eye will be lost in the middle of the chart without them, and the data will be seen quite approximately, which defeats the purpose of the chart.
- In one of
the charts there is no legend to follow.
- X axis legend aligned to the center will be lost on wide screen.
- Y axis legend aligned to the right will be lost on all screens.
- Stroked circles look like a radio buttons. Use them for interactivity, if you want, but for static version circles should be filled.
- Shapes (stroked circles & full circles) should be cohesive for full charts and mini-charts. Each shape represents one type of variable, and you have two different variables shown when you show both.
- Shades of blue-green & blue are
too close and blend in together. I suspect you didn't validate chart
colors for color-blind users, either.
I've designed the reference to illustrate these points (see below).
As I see it, your biggest problems lie in the scope of legend design, where function goes before the form, and this is relatively easy to fix. I highly recommend Tufte's books, blog and forum for the fastest internalization of common pitfalls.
As for the interactivity level, there are way too many possibilities that will depend on the data that you have, the data you want to show, the insights you would want to highlight, and user needs. It is better to ask separate specific questions regarding specific issues, like you did with these charts.
