# Isotype × Schematic Transit Diagram — composed image prompt
# IndexStyle — https://indexstyle.org/compose?ids=isotype+transit-diagram
# Isotype carries the structure. Schematic Transit Diagram appear as accents, each further back than the last.
# Style descriptors only. Never imitates a specific artist, studio, brand or work.

An original image that takes its structure from Isotype (Layout, 1920s–1940s) and its accent from Schematic Transit Diagram (Layout, 1933–). Structural cues: Unified pictograms; Repetition of signs; Axes of comparison; Restricted color. Accent cues, used sparingly: Lines limited to 45 degrees; Evenly spaced stations; Color-coded lines; Independence from geography. Composition: Fix the unit per symbol; show change by count, never by size. Type and lettering: Short labels and clear figures; prose stays outside the chart. Let one material quality come from the second style: One color per line, white circles for interchanges, plain background behind. Mood: Trust, Technology, Intimacy, Calm. Color: build on #eee7d3, #b9362c, #2c4e72 with a single accent drawn from #e9e6dd, #67635d, #171615. Constraints: do not imitate, reference or name any specific artist, studio, brand, character or copyrighted work. Produce an original composition in the general period languages described above.

# Where the two fight
# - Both belong to Information Design, so the difference is small. Push the roles further apart than feels comfortable.

# Cautions carried from each entry
# - Isotype: Never scale one big symbol to show a difference. Always show unit, base and source.
# - Schematic Transit Diagram: Trying to keep a little geographic accuracy breaks the angle rule, and the diagram ends up neither accurate nor easy to read.
