Massachusetts safe town/city selector by county and community

This interactive visualization helps users select safe towns and cities across Massachusetts by filtering crime data by county or community type. The map displays the top five lowest crime-rate areas for any chosen selection, with circle size proportional to crime ratio and hover tooltips revealing additional details. Built with React and D3, the visualization uses d3.geoPath with a geoAlbers projection to render Massachusetts county boundaries from TopoJSON data, while d3.scaleSqrt sizes the crime-rate circles over the state map. Crime statistics come from a 2016 Massachusetts crime dataset.

Massachussetts Top 10 Crime City filter works

This interactive bar chart displays the crime rates of Massachusetts cities, filterable by community type (All, City, Rural, Suburb) via a dropdown menu. Built with React and D3 v5, it renders an SVG visualization where each bar shows the crime rate as a percentage. The chart loads data from a CSV file containing 2016 crime statistics, using D3's `csv`, `scaleBand`, `scaleLinear`, and `format` functions for data processing and axis scaling. The top 10 cities are displayed by default, with tooltips revealing precise percentage values.

Mass Crime Map with circle size corresponding to crime/population ratio

This map of Massachusetts towns shows crime rates as circles overlaid on geographic boundaries, with circle size scaled to each town's crime-to-population ratio. Using React and D3 v5, the visualization projects GeoJSON features onto an SVG canvas via d3.geoPath with a geoAlbers projection, while d3.scaleSqrt maps crime rates to circle radii. Crime data comes from the FBI’s 2016 table, and geographical boundaries derive from MassGIS shapefiles converted to TopoJSON. Hovering reveals city, county, and exact crime rate in the tooltip.
