Map Reviews: 4/5 Stars

  • Easy for searching information from different neighborhood with mulit-level map design.
  • Detailed information with bar chart and statistic report.
  • Categories legend serves as a filtering feature.

Though the map can be improved if map users can be directly directed to the neighborhood after clicking the region since the popup box with the inserted URL is a bit superfluous and meaningless.

Overall, there are few crime maps are really informative, and it ‘s one among the minority.
