ClusterChirp: A GPU-accelerated Web Server for Natural Language-Guided Interactive Visualization and Analysis of Large Omics Data.

Tabular datasets are commonly visualized as heatmaps, where data values are represented as color intensities in a matrix to reveal patterns and correlations. However, modern omics technologies increasingly generate matrices so large that existing visual exploration tools require downsampling or filtering, risking loss of biologically important patterns. Additional barriers arise from tools that require command-line expertise, or fragmented workflows for downstream biological interpretation. We present ClusterChirp, a web-based platform for real-time, interactive exploration of large-scale data matrices enabled by GPU-accelerated rendering and parallelized hierarchical clustering using multiple CPU cores. Built on deck.gl and multi-threaded clustering algorithms, ClusterChirp supports on-the-fly clustering, multi-metric sorting, feature search, and adjustable visualization parameters for interactive explorations. Uniquely, a natural language interface powered by a Large Language Model helps users perform complex operations and build reproducible workflows from conversational commands. Furthermore, users can select clusters to explore interactive within-cluster correlation networks in 2D or 3D, or perform functional enrichment through biological knowledge bases. Developed with iterative user feedback and adhering to FAIR4S principles, ClusterChirp empowers researchers to extract insights from high-dimensional omics data with unprecedented ease and speed.
