This bar chart visualizes the latest temperature readings from seven cities, using live data from the Data Canvas - Sense Your City API. Built with D3 v3 and an SVG rendering approach, it follows a reactive model-based architecture: the chart derives its width, height, scales, and axes from a set of properties, automatically updating when data or configuration changes. The X axis displays city names sorted by temperature, while the Y axis encodes the temperature values. The visualization includes animated transitions, a title, and axis labels, and is implemented as a reusable module that supports sorting and customizable margins. The data updates every five minutes, reflecting the most recent sensor readings.

AI-generated description

This program makes a bar chart from data in the Data Canvas - Sense Your City API.

This shows the temperature for all cities with available data. The data is up to date, and updates every 5 minutes.

Based on Data Canvas Part 2 - Line Chart

The reactive flow of the bar chart. The diagram was constructed using the reactive flow diagram renderer.

Colors

This example uses the Sense Your City API to visualize temperature data from seven cities. A line chart shows temperature trends over the past 24 hours for each city, while a bar chart displays current temperatures. Colors code the lines to the city, with palettes generated automatically using the LAB color space for optimal distinctness. The visualization updates every five minutes, and the line and bar charts are built with reusable D3.js modules, animated via SVG.

Line Chart

This line chart visualizes temperature readings over time for Geneva, automatically updating every 5 minutes with data from the Data Canvas - Sense Your City API. The chart is built with a reusable D3.js module and uses SVG rendering with smooth transitions. It fetches aggregated CSV data (mean temperature by date) via jQuery, maps the date field to a time-scale X axis and temperature to a linear Y axis, and includes labeled axes and a title. The visualization supports dynamic resizing and live data updates through a Model-based architecture that coordinates the container, SVG dimensions, scales, and axes.

Untitled

A bar chart displays five daily temperature readings in San Francisco, ranging from 0.9 to 2.5 degrees Celsius, using blue bars of proportional height. The visualization encodes values with a linear scale and renders static SVG rectangles, with an axis generated by `d3.axisBottom`. It uses D3 v5 to bind the dataset, scale the bar widths, and append a bottom axis with four ticks. The data is a small sample from the Data Canvas - Sense Your City project, though the chart only shows these five arbitrary values without labels for dates or units.

MULTILINE CHART

This multiline chart displays one week of temperature data across multiple global cities, sourced from Data Canvas - Sense Your City. The visualization uses d3.scaleTime, d3.scaleLinear, and d3.scaleOrdinal to map timestamps, temperatures, and city colors, while d3.nest groups readings by city and d3.line with curveBasis draws smoothed paths. An interactive color legend, built with a custom colorLegend function, identifies each city. The SVG rendering includes responsive axes with grid lines, and stroke blending via mix-blend-mode: multiply enhances line overlap.

Line Chart

This interactive line chart displays temperature trends over time from the Data Canvas Sense Your City dataset. The visualization uses React to render an SVG graph with time-scaled x-axis and linear-scaled y-axis, applying a natural curve to connect data points smoothly. D3 v5 utilities generate the axes and line path, while React hooks load and parse the CSV data. The chart includes labeled axes showing days on the horizontal axis and temperature values on the vertical axis, with a clean, minimal design emphasizing the data pattern.

Visualization Editor

This visualization editor presents a live scatter plot and line chart showing temperature and humidity data for seven cities, fetched from the Data Canvas Sense Your City API. The scatter plot maps humidity against temperature with lines connecting city-specific series, while the line chart shows temperature trends over time. Users can interact with a configuration editor pane, adjusting visualization parameters through Chiasm’s reactive model, built with D3.js, CodeMirror, and the Inlet library. The runtime loads data continuously in 24-hour intervals, displaying five-minute resolution records with SVG rendering.

Several City Chart

A week of temperature readings for several cities is displayed as overlapping, semi-transparent lines on a time-series chart, with a color legend identifying each city. The lines are ordered by their final temperature values using `d3.nest()` and a descending sort. The visualization uses D3 v5 with SVG rendering, including `d3.scaleTime`, `d3.scaleLinear`, `d3.scaleOrdinal`, `d3.line` with a basis curve, and axis components. Data is loaded from a CSV via `d3.csv` and formatted with `new Date` and numeric conversion.

Temperature in Different Cities

This visualization presents a small multiples area chart tracking temperature readings across seven cities over one week in 2015, using data from the Sense Your City project. The design intentionally demonstrates an ineffective approach to data visualization: color encoding is arbitrary, the area under each curve holds no quantitative meaning, and comparing values across the separate faceted charts proves difficult. Built with Vega-Lite 2.0 and D3 v4, the code constructs the specification programmatically, loading CSV data via `d3.csv` and rendering the output through `vegaEmbed`. Each city occupies its own row, with temporal timestamps on the x-axis and temperature in degrees Celsius on the y-axis, while grid lines are disabled to simplify the display.
