Clustergrammer-GL Roadmap

Clustergrammer-GL is a JavaScript library that produces interactive heatmaps using the WebGL library regl. Clustergrammer-GL's primary use is as dependency of Clustergrammer2, which is a Jupyter Widget data analysis and visualization library built to analyze single cell high-dimensional biological datasets. Our goals are:

• improve the interactive visualizations produced by Clustergrammer-GL and the Jupyter Widget Clustergrammer2
• improve the front-end data analysis capabilities of Clustergrammer-GL (e.g. front-end re-clustering)
• integrate Clustergrammer-GL into Clustergrammer-Web to enable visualizations of larger datasets on the web application

Single Cell Data Visualization

Clustergrammer-GL is primarily being developed to facilitate the analysis of single cell biological datasets and has certain default behaviors (e.g. row gene information lookup on mouseover, enrichment analysis).

• export genes to Enrichr: ismms-himc#18

Use within Jupyter Widget

We are setting up generalizable callback functions that will enable two-way communication to the Python kernel using the Jupyter Widget infrastructure.

• allow callback functions https://github.com/ismms-himc/clustergrammer-gl/issues/new?assignees=&labels=&template=feature_request.md&title=

High Dimensional Single Cell Data Visualization

Clustergrammer-GL is primarily being built as a dependency of Clustergrammer2, a single-cell data analysis toolkit. However, we are developing Clustergrammer-GL to be generalizable. We want Clustergrammer-GL to be useful for exploring datasets outside of biology (e.g. financial), embeddable into other contexts (e.g. custom web applications), and independent of a Python back-end (e.g. run clustering on JavaScript]). Issues associated with these goals are:

• front-end clustering ismms-himc#1
• value-based category histograms ismms-himc#31

Issues

High Priority

• category bleedthrough
• dendrogram slicing of linkage matrix
• camera update
• slow scrolling speed
• row/column search

Normal Priority

• improve text cutoff
• dendrogram interactions
• tooltip overflow
• callback functions on common interactions
• initial ordering button
• category updating for Enrichrgram
• brush select zoom
