This interactive visualization depicts the 2017 US Federal Budget as a bubble chart, where each circle represents an agency and its size encodes the agency’s budget (via a square-root area scale). The data comes from a CSV of federal outlays. Users can toggle two checkboxes to regroup the bubbles: “Group by BEA Category” aligns circles along the x-axis according to their BEA category, and “Group by Grant” arranges them along the y-axis by grant/non-grant split. When neither box is checked, a force simulation lets the bubbles drift freely; enabling one or both checkboxes applies x- and y-position forces to cluster the circles into the corresponding categories, with axes appearing as needed. Tooltips reveal the agency name and its 2017 budget in millions of dollars. The visualization uses D3 v4 with an SVG renderer and a force-directed layout, scaling bubble area by budget.
