Gun Deaths in Florida

This visualization tracks the annual number of firearm-related murders in Florida from 1989 to 2016, highlighting the period after the 2005 enactment of the “Stand Your Ground” law. A dark red area chart with a heavy black line and a single point at 2005 emphasizes the trend and the policy milestone. Built with D3 v5, it uses SVG paths generated by `d3.area()` and `d3.line()`, plus `d3.axisBottom` and `d3.axisLeft` for labeling, with data from the Florida Department of Law Enforcement.

Mobility Rate Bubble Chart

This bubble chart displays the mobility rate of California universities, plotting median parent household income against the percentage of students from the bottom income quintile who reach the top. Circle size represents average cohort size, while diverging color scales encode trends in parent income distribution. The D3.js v5 visualization uses `d3.scaleSqrt` for radius, `d3.scaleDiverging` for color, and d3-legend for legends. Data comes from Opportunity Insights' Mobility Report Cards, rendered as SVG elements with labeled circles and average reference lines.
