Is your feature request related to a problem? If so, please describe.
Yes. The Data Overview panel loads summary statistics and feature distribution charts for the entire uploaded dataset with no limit on how many features are shown. On wide datasets (many hundreds or thousands of columns), the panel becomes slow to load, heavy in the browser, and difficult to scroll through.
Example workflow: I upload a wide tabular file and land on Data Overview as the default view. The page tries to render a full summary table and a distribution chart for every numerical feature at once. The wait is long, the page feels unresponsive, and scrolling through thousands of rows and images is impractical.
The Readiness Report already limits how much detail it shows for very wide datasets, but the separate Data Overview panel does not apply similar bounds.
Describe the solution you'd like
Keep Data Overview useful on wide datasets by paginating both major content areas instead of rendering everything at once:
- Summary statistics table — show a fixed number of features per page (e.g. 25–50), with page controls and a clear label such as “Page 2 of 48 · 2,341 features total.”
- Feature Distributions — paginate histograms the same way, loading only one page of charts at a time rather than every distribution in a single long grid.
- Totals always visible — record count, total feature count, and numerical/categorical breakdowns should still reflect the full dataset, even when the table and charts are paginated.
Optional follow-ups (not required for a first version): let users change page size, jump to a feature by name, or sort which features appear first (e.g. alphabetical vs. highest missingness).
Describe alternatives you've considered
- Hard cap with a truncation message only — simpler to build, but users cannot browse beyond the first slice without leaving Data Overview.
- Point users to the Readiness Report for wide files — avoids work on Data Overview, but Data Overview is the default landing view after upload.
- Remove Feature Distributions from Data Overview — reduces load, but loses useful at-a-glance context for normal-sized datasets.
- Lazy-load charts on scroll (infinite scroll) — can work, but pagination gives clearer navigation and more predictable performance on very wide tables.
Additional Information
- Affects the Data Overview panel shown after file upload (summary table + Feature Distributions section).
- Problem is most noticeable on wide datasets; typical datasets with tens or low hundreds of features are less affected.
- Pagination should apply consistently whether the data is loaded locally or via remote compute (e.g. Globus), if that path feeds the same panel.
