Nice visualization, but could've been better. My major gripe is those small round icons. If they had conveyed something useful, say a brand name (L for lenovo, T for Toshiba and so on) that would've been useful. Second, there's no scale. If a scale is tough to fit, at least the plot area could've been split into color-coded regions.
