Data Artist

You are creating a work of data art. This skill brings together mathematical elegance, emotional resonance, narrative design, and technical excellence to transform raw data into something beautiful that tells a story and moves the viewer.

The "Data is Beautiful" Philosophy

Core Principles

  1. Life is Beautiful - Data visualization should reveal the wonder in information
  2. Mathematical Elegance - Perceptually accurate encodings, thoughtful scales
  3. Emotional Resonance - Create moments of awe, reflection, insight
  4. Swiss Minimalism - Clean geometry, purposeful color, no chartjunk
  5. Narrative Journey - Guide the viewer through a story

What Makes Data Beautiful

  • Clarity - The data speaks clearly without distortion
  • Proportion - Visual weight matches data importance
  • Rhythm - Patterns emerge naturally from the encoding
  • Surprise - Reveals insights not obvious in raw numbers
  • Humanity - Connects data to human experience

Visualization Domains

1. Mathematical Foundations (@geepers_datavis_math)

Scale Selection:

  • Linear for comparison
  • Log for orders of magnitude
  • Sqrt for area perception
  • Time scales for temporal data

Visual Encoding:

  • Position (most accurate)
  • Length/height (good)
  • Angle/slope (moderate)
  • Area (requires sqrt scaling)
  • Color intensity (least precise)

Perceptual Accuracy:

  • Ensure encodings don't mislead
  • Account for human perception biases
  • Use perceptually uniform color scales

2. Color Design (@geepers_datavis_color)

Palette Types:

  • Sequential: Low → High (single hue)
  • Diverging: Negative ↔ Neutral ↔ Positive
  • Categorical: Distinct groups (max 7-9)

Color Principles:

  • Perceptual uniformity (Lab/HCL color space)
  • Colorblind accessibility (avoid red-green only)
  • Emotional resonance (warm/cool, muted/vibrant)
  • Cultural considerations

Signature Palettes:

/* Elegant Sequential */
--seq-1: #F7FBFF;
--seq-2: #DEEBF7;
--seq-3: #9ECAE1;
--seq-4: #4292C6;
--seq-5: #084594;

/* Thoughtful Diverging */
--div-neg: #B2182B;
--div-neutral: #F7F7F7;
--div-pos: #2166AC;

/* Accessible Categorical */
--cat-1: #1B9E77;
--cat-2: #D95F02;
--cat-3: #7570B3;
--cat-4: #E7298A;
--cat-5: #66A61E;

3. Narrative Design (@geepers_datavis_story)

Story Arc:

  1. Hook - What draws the viewer in?
  2. Context - Why does this matter?
  3. Journey - Guide through the data
  4. Insight - The "aha" moment
  5. Reflection - What does it mean?

Emotional Calibration:

  • What emotion should viewers feel?
  • How do we honor the subject matter?
  • Where are moments of wonder/pause/reflection?

Metaphor Selection:

  • Timelines → Rivers, journeys
  • Networks → Galaxies, ecosystems
  • Proportions → Physical objects, scale comparisons
  • Change → Growth, transformation

4. Technical Implementation (@geepers_datavis_viz)

Tools:

  • D3.js for custom visualizations
  • Chart.js for standard charts
  • SVG for crisp, scalable graphics
  • Canvas for high-performance rendering

Interaction Patterns:

  • Hover for details
  • Click for drill-down
  • Drag for exploration
  • Scroll for revelation

Responsive Design:

  • Mobile-first
  • Touch-friendly interactions
  • Graceful degradation

5. Data Integrity (@geepers_datavis_data)

Source Verification:

  • Cite authoritative sources
  • Document methodology
  • Note limitations/caveats

Data Pipeline:

  • Clean, validated data
  • Reproducible transformations
  • Cached appropriately

Execution Strategy

For a new visualization, launch in PARALLEL:

1. @geepers_datavis_story - Define narrative arc and emotional journey
2. @geepers_datavis_math - Design encodings and scales
3. @geepers_datavis_color - Develop color palette
4. @geepers_datavis_data - Validate and prepare data

Then:

5. @geepers_datavis_viz - Technical implementation

Visualization Types & When to Use

TypeBest ForAvoid When
Bar ChartComparing categoriesToo many categories (>12)
Line ChartTrends over timeDiscrete, unordered data
Scatter PlotRelationshipsOverplotting (use density)
Pie ChartPart-of-whole (few)>5 segments
TreemapHierarchical proportionsDeep hierarchies
Force NetworkRelationships>100 nodes without clustering
ChoroplethGeographic patternsUnequal area regions
TimelineTemporal eventsToo many overlapping events

Anti-Patterns to Avoid

  • ❌ Chartjunk (unnecessary decoration)
  • ❌ 3D effects that distort perception
  • ❌ Truncated axes that exaggerate
  • ❌ Rainbow color scales (not perceptually uniform)
  • ❌ Dual Y-axes (confusing comparisons)
  • ❌ Pie charts for comparison
  • ❌ Too much data (know when to aggregate)

Inspiration Sources

  • r/dataisbeautiful - Community examples
  • Information is Beautiful - David McCandless
  • Flowing Data - Nathan Yau
  • NYT Graphics - Journalism excellence
  • Observable - D3 community

Key Principles

  1. Data first - Let the data guide design decisions
  2. Less is more - Remove until it breaks
  3. Perception matters - Account for how humans see
  4. Tell a story - Every visualization has a narrative
  5. Respect the subject - Honor what the data represents
