Data explorer
Slice two years of orders any way you like and see what changed, without waiting on a report.
A working demo for Ridgeway Logistics, an invented business. All data is made up and nothing you enter leaves this page.
Try it
- Pick a measure, group by one dimension and split by another
- Switch between line, bar, heatmap and a sortable table of the same numbers
- Filter to High Plains pallet freight and compare May 2026 with April, when a large claim left a negative base
- Copy the link to share the view, or export it as CSV
Under the hood
- Order lines are stored as typed columns sorted by day, so a re-slice reads only the days asked for
- Changes against the previous period handle zero and negative bases instead of dividing by them
- Averages are computed from summed totals, never averaged again
- Every chart is plain SVG with a description and a table of the same numbers
Built with React, TypeScript, SVG, Vitest.
The same skill in production work
- Built a clinical analytics dashboard from scratch that shows, for any facility, whether each field arrives where reporting and billing expect it, and turns HL7 messages into facility metrics from daily to yearly without putting a patient's details on screen.
- Indexed lookups on a table searched on nearly every keystroke return in about a millisecond.
