The Belonging Tree is an interactive installation and web-based data visualization that explores global interconnectedness and identity through migration and movement. Framed as a collaborative digital artwork, the project invites participants, especially those with multicultural backgrounds, to reflect on the countries that have influenced their sense of self. Through individual inputs, users contribute to the growth of a shared, evolving tree, where each entry becomes part of a collective structure. By aggregating personal narratives into a living visualization, The Belonging Tree reveals that despite our varied backgrounds and the many places we come from, we are united by a shared humanity—seeking connection, meaning, and a sense of belonging in the same world.
