Lock visual language v1 with RJ

Problem

Dataface's visual identity for charts is currently a set of working defaults that evolved during prototyping — there is no finalized, intentionally designed visual language. Typography choices, color palettes, grid styling, axis aesthetics, and interaction defaults (hover behavior, transition timing, selection states) have not been reviewed by a professional data visualization designer. Without locking a v1 visual language with RJ Andrews, the chart library risks launching with generic-looking output that is indistinguishable from off-the-shelf tools, losing the differentiation that is central to the product's value proposition.

Context

• The chart library has promising defaults but no formally locked visual system reviewed with RJ.
• Several adjacent tasks already explore typography, palettes, style systems, and chart-family decisions that should roll up here.
• This needs a concrete design decision set, not an endless exploration loop.

Possible Solutions

• A - Keep iterating informally and let the visual language emerge from implementation work: flexible, but inconsistent.
• B - Freeze the current defaults quickly without dedicated design review: fast, but weakly justified.
• C - Recommended: consolidate the existing chart-design work into a deliberate v1 decision set reviewed and signed off with RJ.

Plan

1. Gather the current visual decisions, open questions, and adjacent task outputs.
2. Review a representative chart set with RJ and resolve the major typography, palette, and interaction choices.
3. Translate the decisions into concrete defaults, tokens, and renderer guidance.
4. Publish the v1 visual language and identify follow-up items that remain outside the launch-critical set.
