This visualization overlays seven nights of FitBit heart-rate data as a multi-series line chart, showing minute-by-minute heart-rate fluctuations during sleep from May 18-24, 2016. Each night is a distinct colored line, plotted over time on the x-axis (hours:minutes:seconds) with beats per minute on the y-axis, revealing patterns like elevated heart rates and nightly variation. The code uses the nv.d3 library's `lineChart` model built on d3.v3, loading CSV data via `d3.csv` and parsing times with `d3.time.format` to construct the series for display with interactive guidelines and tooltips.

basic sleep data

This interactive scatter plot visualizes sleep duration and bedtime across moon phases, with each bar representing one night of Fitbit sleep-tracking data. The x-axis marks moon phase values from 1 to 29, while the y-axis displays time of day, showing end-of-sleep hour and duration in hours. The React app uses `scaleBand` and `scaleLinear` from d3.v5 to position rectangular marks in an SVG. Data is fetched asynchronously from a JSON gist, with moon phases calculated via a simple algorithm and timestamps parsed using `timeFormat`.

intermediate sleep data

This interactive sleep data visualization charts nightly sleep duration against lunar phase. Rectangular marks show the end time and duration of each sleep session, while moon phases from new moon (1) to full moon (15) run along the x-axis. The SVG rendering uses React with D3 scales (scaleBand, scaleLinear) and custom axis components. Data is fetched from a Fitbit JSON file and processed client-side to calculate moon phase conversions, remove errant values, and unify duplicate days before sorting and averaging.

Sleep Cycles

This visualization plots daily sleep intervals across seven months, showing when a person falls asleep and wakes each day as a stepped horizontal bar. The y-axis represents time of day from evening to morning, while the x-axis shows the calendar date. The code converts each sleep interval into elapsed milliseconds since midnight and uses `d3.scaleUtc`, `d3.area`, and `d3.axisLeft` with SVG rendering. The fake data is loaded from a CSV file and parsed using `d3.utcParse`.

Fork of blood pressure

This visualization shows the relationship between age and sleep duration for a group of individuals, with each person represented as a point on a scatterplot and connected by a smooth line. The chart uses D3.js v5 to load CSV data from a GitHub gist, parse the numeric fields, and render the SVG visualization. It employs `d3.scaleLinear` for both axes, `d3.axisBottom` and `d3.axisLeft` for tick marks, and `d3.line` with `curveBasis` to create the curved trend line. The line is styled in maroon with a thick stroke, while gridlines and axis labels are formatted with custom CSS. The data source is a public dataset on sleep health and lifestyle.

Scatter Plot of Hours Slept

A scatter plot compares hours slept against a lunar phase, with each individual night a gray circle and the average per phase a green circle. A bar chart underlying the plot uses the same axes. The React app fetches Fitbit sleep data, processes it with D3 v5’s `scaleBand` and `scaleLinear`, and renders SVG via React components for axes and circle marks. Moon phase values derive from a simple JavaScript calculation.

Sleep Cycles

This visualization plots a person’s daily sleep intervals as a time-series graph in the style of Eric Boam’s “Seven Months of Sleep,” covering seven months of synthetic data. The y-axis shows time of day from evening to morning, while the x-axis spans consecutive dates, with each sleep period rendered as a filled step-area region. The code uses d3.scaleUtc and d3.utcFormat for time axes, d3.area with a step-after curve for the shapes, and parses the CSV data with d3.utcParse. The data is generated by a Node script using d3.randomNormal.

Gist 23c3fa2ac8adc645fc6c6d7a2d761a88

The visualization tracks daily exercise duration across May 2017, showing a repeating pattern where every fourth day records zero minutes. It uses a line chart built with D3.js, plotting dates on the x-axis and minutes on the y-axis via `d3.scaleTime` and `d3.scaleLinear`. The code reads the CSV data from the gist and draws circles and connecting lines, with resting days highlighted by points at zero. The chart emphasizes the regularity of rest intervals amid fluctuating workout times, sourced directly from the uploaded CSV file.

Gist a47a4a5c5f7039022881d0b2dc84a1d6

The visualization tracks a month of daily running activity, plotting each day’s distance, time, and heart rate as a dual-axis scatterplot with a connected line. It shows how distance and time peak on high-mileage days while resting heart rate dips, with zero-distance rest days marked as gaps. Built using d3.scaleLinear for axes, d3.line for the path, and d3.axisBottom/axisLeft for gridlines, the chart reads from the CSV data via d3.csv. Points are rendered with d3.point circles, and the y-axis encodes time, while the x-axis uses a time scale for dates.
