This visualization gallery presents multiple interactive charts analyzing open-source contributor activity and missing children statistics in India. The main network graph maps author collaboration patterns, with node size reflecting commit counts and colored links showing repository co-contributions. Interactive tooltips provide detailed author metrics on hover, while zoom capabilities are implemented through `d3.zoom()`. Additional charts include horizontal bar charts ranking repositories by commit volume using `d3.rollups` for aggregation, stacked bar charts displaying missing children data by gender across states using `d3.stack()`, and sequential color scales (`d3.scaleSequential`) to encode crime rates per capita. All visualizations employ D3.js v7 with SVG rendering, `.join()` operations for data binding, and `transition()` methods for smooth hover animations.
