This interactive tree diagram maps the corporate and financial entities that Corporate Watch identifies as major drivers of climate change, organizing them by sector such as oil and gas, finance, and the ideology industry. Using D3 v7, the visualization employs a collapsible hierarchy with animated transitions, where nodes are rendered as SVG rectangles and connecting links as curved paths. Users can expand and collapse branches to explore the data structure, which includes details on company addresses and environmental impact sourced from the provided CSV file.
