Smart City Dashboard Designer
Build a dashboard that helps an operator see what is happening, trust the data, and act before a city service breaks down. Change the scenario and assumptions to see how widgets, update rates, thresholds, and edge aggregation change the result.
6 widgets Dashboard scope
0.6 s Estimated alert latency
78% Operator readiness
Try Select Utilities, set Sensors to 500, Update interval 5 s, and Widgets to 6 before Stress test.
Observe Estimated bandwidth and operator load rise as sensors refresh faster; Edge aggregation cuts traffic but can remove raw detail. Step confirms this readout.
Explain Role-specific dashboards turn measurements into decisions, while rate, aggregation, thresholds, and widget count set data and cognitive load. Step exposes this mechanism.
Technical boundaries The score omits user testing, map cost, alert history, data gaps, topology, access control, incident workflow, and procurement.
Colour key
Start with a decision
A dashboard is useful only when it supports a clear action: dispatch, investigate, adjust service, or escalate.
Choose fewer widgets
Operators scan under pressure. Six to eight well chosen widgets usually work better than a wall of charts.
Aggregate before display
Thousands of sensors should feed summaries, trends, and alerts. Raw readings are for drill-down, not the first screen.
Tune alerts carefully
Warning and critical thresholds need separation, context, and hysteresis so teams do not ignore noisy alarms.
1. Decide Pick the operational decision.
2. Sense Collect city signals.
3. Aggregate Filter and summarize at the edge.
4. Visualize Select widgets for quick scanning.
5. Alert Separate warning from critical action.
6. Improve Review outcomes and tune thresholds.
Animated Dashboard Build
Start with the city decision before choosing visual widgets.

Data load
0 kbps
Sensor count, payload size, interval, and edge aggregation decide the stream reaching the dashboard.
Operator load
Balanced
Widget count, map density, and update speed affect how hard the first screen is to scan.
Recommendation
Start focused
Use a role-specific first screen and keep drill-down detail one click away.
Experiment Controls
Choose a city service, then change one dashboard assumption at a time. The animation, metrics, diagnostics, and formula trace update together.

Reference Material
Use these cards as a checklist when designing dashboard sections in smart city chapters or exercises.
Widget Selection Quick Reference
KPI card Best for one operational number that must be scanned quickly, such as congestion score or open incidents.
Trend chart Use when the direction matters. Keep the time window aligned with the decision being made.
Map Useful when location changes the response. Avoid making the map the whole dashboard unless field dispatch is the main task.
Alert panel Show active warnings, critical alerts, owner, age, and suggested next action. Do not show alerts without ownership.
Table Good for drill-down and audit work. Tables are rarely the best first widget for live operators.
Forecast Useful for planners and utilities when forecast uncertainty is visible and not presented as a certain outcome.
Operations Design Guide
Role-specific view Operators need action now, planners need patterns, field crews need location and instructions, executives need summary risk.
Progressive disclosure Put the decision summary first. Keep raw sensor detail, logs, and long tables behind drill-down controls.
Refresh cadence Match refresh rate to operational need. Updating every second is wasteful for hourly waste collection planning.
Alert ownership Every critical alert should indicate who acts, by when, and what evidence justified the alert.
Accessibility Do not rely on color alone. Use labels, icons, contrast, keyboard focus, and readable target sizes.
Mobile field use Field crews need responsive layouts, offline fallback, simple location context, and large touch targets.
Technical Accuracy Notes
Normalized thresholds This teaching model uses a 0-100 pressure score. Real domains use specific units such as AQI, minutes, amps, or fill level.
Aggregation Dashboards should query aggregates for first-screen views. Raw streams are expensive and noisy at city scale.
Alert fatigue Warning and critical thresholds need separation and hysteresis. Otherwise small signal noise can toggle alerts repeatedly.
Latency estimate The latency here is a planning estimate, not a benchmark. Real latency depends on network, broker, database, and query design.
Privacy Camera, mobility, and safety data can become sensitive. Aggregate, anonymize, restrict access, and audit use.
Security Use authentication, authorization, TLS, logging, and least-privilege access for operational dashboards.
