CHARTMAKER · FEEDS · CROSS-CHARTS

Make the daily chart weirder, richer, and more useful.

Chartmaker is the lab behind Chart of the Day: PointCast data first, then add weather, stocks, sports, feeds, and local-only memory as chartable lanes.

V3 · REMIX DESK

Chartmaker v3

A daily board should not just show isolated charts; it should suggest useful crossovers that can become tomorrow’s app surfaces.

Promote one remix into a live Chart of the Day variant.

TODAY BOARD · Tuesday, May 5, 2026

10 charts for today

Crypto Mood

BTC, ETH, and XTZ are all green in the sampled 24h change feed.

REMIX QUEUE

5 crossovers worth building next

local

Marine Layer Shipping

Local atmosphere plus PointCast output turns the day into a readable field note: cool air, clean enough sky, small waves, one shipped receipt.

Make a combined weather x shipping chart with blocks as bars and temperature, AQI, and wave height as small overlay lanes.

Risk-On Collectibles

AAPL, TSLA, BTC, ETH, and XTZ give a quick public-market mood without turning the app into a finance product.

Add a non-advice market mood badge to /now and pair it with mint/collector surfaces only as context.

Sports Evening Stack

The evening has a clean sports rhythm: two NBA games, a dense MLB slate, and enough internet culture to make a watch-card feel alive.

Build a single live scoreboard strip that can choose NBA or MLB based on active games.

USGS, marine forecast, and NASA APOD make Chartmaker feel bigger than local productivity: earth, ocean, sky.

Agent Source Readiness

This lane tests whether agents can explain the day from mixed sources without overclaiming: ledger facts, public APIs, and cultural prompts.

Add confidence labels per chart: native, public no-key, sampled, candidate, local-only.
