This bubble chart visualizes monthly visitor counts for four cultural sites in Los Angeles from 2014 to 2016. Each circle represents a month, positioned along the x-axis by date and y-axis by the number of visitors to the America Tropical Interpretive Center. The circle’s radius encodes Avila Adobe visitor numbers using a linear scale. Built with React and D3 v7, the SVG visualization uses `d3.scaleTime` and `d3.scaleLinear` for axes, with hover tooltips displaying specific values.
