# Schematic Transit Diagram carries the structure. Weather Map 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 Schematic Transit Diagram (Layout, 1933–) and its accent from Weather Map (Style, 1851–). Structural cues: Lines limited to 45 degrees; Evenly spaced stations; Color-coded lines; Independence from geography. Accent cues, used sparingly: The density of isobars; Cold and warm front symbols; The weather-symbol system; Highs and lows labeled. Composition: Only horizontal, vertical and 45 degrees, even spacing, widened where stations crowd. Type and lettering: Set station names at one constant angle in a single face and size. Let one material quality come from the second style: The base map held pale, only lines and symbols brought forward. Mood: Trust, Technology, Calm. Color: build on #e9e6dd, #67635d, #171615 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
# - Roughly 82 years apart. Keep one of them recognisably period rather than letting both drift into the middle.

# Cautions carried from each entry
# - 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.
# - Weather Map: Changing the isobar interval from day to day destroys the cue that lets a reader judge wind strength from how crowded the lines are.
