This histogram displays the distribution of a selected weather-related column, such as temperature, from a San Francisco weather dataset. The chart updates with smooth transitions when a different input column is chosen from a dropdown menu or when the bin count is adjusted via the number input. Built with React and D3 v5, it renders as SVG and uses `d3.histogram`, `d3.scaleLinear`, and `d3.axisBottom`/`axisLeft`. Interactive tooltips highlight each bar and show its class range and frequency on mouseover.
