If you wanted to run a Pandas analysis or generate a Matplotlib chart, you had to send data to a server, process it, and send the results back.</p> <p>But with the rise of <a href="https://webassembly.org/">WebAssembly (<code>WASM</code>)</a>, that boundary is blurring.</p> <p>In this project, I built <strong>SveltePy Studio</strong>, a fully client-side application that brings the power of Python&rsquo;s data science stack directly into the browser. By combining <a href="https://kit.svelte.dev/">SvelteKit</a> for a reactive UI with <a href="https://pyodide.org/">Pyodide</a>—a port of <a href="https://github.com/python/cpython">CPython</a> to WebAssembly—users can upload CSV datasets and generate complex visualizations without a single byte of user data leaving their device.</p>
