Return to the opening question: “Is this neighbourhood convenient?” We can now give a more useful response: convenient for whom, for which activities, and measured how? The maps have not failed to answer a simple question. They have helped us recognise the decisions inside it.

The worked sequence begins with observed housing prices, introduces nearby stops and activity, then distinguishes amenity categories. The comparison shows why a familiar proxy can be incomplete: the Tampines and Woodlands illustrations have equal 500 m stop counts but very different boarding totals. The radius comparison then challenges the apparent firmness of a nearby-facility count. The ending asks the reader to specify a need before selecting a measure.

This is the chapter’s central idea: define convenience before comparing places. Its human relevance comes from a recognisable decision. Its tension comes from a checked contrast. Its payoff is an improved way of evaluating evidence. The narrative has a purpose without manufacturing a winner or claiming that proximity determines price.

A complete short-form version

A book chapter gives room for explanation. A six-panel slide sequence or short web story must carry the same logic more economically. Use the six-frame plan in Section 7.1 as a starting point. Test the finished sequence against three questions:

A compelling final paragraph might read:

These maps offer several views of the same city. Housing prices describe observed sales. Stop counts describe nearby records. Boarding totals describe transport activity. Amenity points describe selected facilities. To judge convenience, first decide which daily need matters, then choose evidence that measures it. A familiar map becomes more useful when we know which question it can answer.

A self-study project

Develop an alternative sequence for a clearly named audience, using the bundled data as a starting point. Keep the analytical core inspectable. Your submission should contain a one-paragraph brief, four to six visual frames, a short methods note, a source list and a paragraph explaining what your story cannot establish.

Begin by selecting a specific need, such as reaching an everyday destination or finding a particular category of facility. Explain why the existing layers do or do not measure that need. If you change the case-selection rule, write it down before inspecting the new results. Retain one sensitivity comparison, such as a radius change or an alternative price measure. Conclude with the claim the evidence actually supports, even if it differs from the story you expected to tell.

Evaluate the work using four questions. Can the reader identify the central question? Does each visual contribute a new inference? Can another student reproduce the displayed numbers? Does the closing statement remain true when read without the surrounding explanations? Good visual communication requires all four.

Data sources and reproducibility

The reproducibility directory contains prepared input tables, original plotting code, an audit and checksums. Analysis uses 500 m and 800 m straight-line radii in EPSG:3414. The local examples are illustrative blocks, not area-wide estimates, statistically tested price effects or neighbourhood rankings.
