SwiftUI-Data-Visualization 2.0.2

Fixed

• SwiftUIDataVisualization.version reads 2.0.2. The 2.0.1 release still reported 2.0.0;
  a released tag cannot change, so the corrected value ships in this release.

Documentation

• The README, its translations, the Accessible Charts article and the AudioGraphDescriptor
  documentation no longer say TreemapChart draws with Canvas; it draws its tiles with plain
  views. RadarChart and LiveTickerChart do draw with Canvas.
• The installation instructions start from 2.0.2.
