This visualization shows a line chart tracking how average fixation duration changes over the course of an eye-tracking experiment with 86 undergraduate students solving math problems. The chart plots response time against experimental order, with data from the WPI MAPLE Lab study, showing whether fixation patterns vary across participants over time. The code uses D3 v7’s `scaleTime`, `scaleLinear`, and line generator, loading data from a CSV file via `csvParse` and rendering axes with reusable `axisLeft` and `axisBottom` functions from the `d3` module.

AI-generated description

This is a dataset from WPI MAPLE Lab study conducted in 2021-2022. 86 undergraduate students solved math problems in the lab and their eye-movements during the solving process were collected with eye-tracking software. Each participant solved 24 problems: 12 with and 12 without brackets.

Data dictionary:

  • Participant_ID' - Anonymized participant ID. Categorical.
  • 'Problem_ID' - Problem title. Categorical.
  • 'Order' - The order of the problem in the experiment. Ordinal.
  • 'Brackets' - If equation contains brackets. Categorical.
  • 'Response_time' - How long did it take fot participant to response. Quantitative.
  • 'Correct_or_not' - If participant’s response was correct ot not. Categorical.
  • 'Average_duration_of_fixations' - How long participant fixated on each digit (on average). Quantitative.
  • 'No_fixation_percentage' - On how many digits participant did not fixate? Quantitative.

The following information could be visualized:

  1. Did average fixation duration change over the time of the experiment? Did it change differently in different participants?
  2. Was response time associated with correctness? Did this association change over the time of the experiment?
  3. Did people tent to answer longer in problems with brackets and did this association change over the time of the experiment?
  4. Was tendency to use peripheral vision associated with response corectness? Did this association change over the time of the experiment?

Experiment AE

This interactive scatterplot explores eye-tracking data from a WPI MAPLE Lab study, showing how problem order relates to metrics like average fixation duration, response time, or no-fixation percentage. Users select the y-axis variable via a menu, and each point is colored by correctness. The visualization uses d3.scaleLinear for axes, d3.scaleOrdinal for color mapping, and displays a red trend line computed via linear regression. Hovering over the d3 color legend highlights correct or incorrect data points. Data is loaded from a CSV and parsed with d3.csvParse.

Scatter Plot Simple - AE

A scatter plot displays the relationship between problem order and average duration of fixations for participants in a WPI MAPLE Lab eye-tracking study. Each circle represents a single math problem solved by one participant, with the x-axis showing the problem's order in the experiment and the y-axis the average fixation duration in milliseconds. The visualization uses d3.scaleLinear and d3.extent to map data values to screen coordinates, with circles rendered via selection joins. Data is loaded from a CSV file using d3.csvParse.

Marks and Channels AE

The visualization displays eye-tracking data from 86 undergraduate students solving math problems, focusing on average fixation duration and response patterns. It shows a simple bar chart where each rectangle’s height represents a data value, with white lines marking the minimum threshold. The example uses d3-selection and d3’s join pattern to render twelve small multiples of the same chart, each built with a reusable `length` function that draws rect and line elements. The fixed dataset contains five pairs of numbers, and the charts are laid out as separate SVG elements with a cadetblue background.

Many plots. Part 1

The visualization is a small-multiple grid of scatter plots, one per participant, showing eye-tracking metrics across 24 math problems. Each plot displays the problem order on the x-axis and a selectable y-axis metric (average fixation duration, no-fixation percentage, or response time), with points colored by correctness. A red trend line shows the linear relationship, and a color legend filters points by hovering. The interface uses a dropdown menu to change the y-axis metric. Data comes from a WPI MAPLE Lab eye-tracking study with 86 students, parsed from CSV and rendered using the d3 library (v7), with helper modules for axes, color legend, and scatter plot rendering.

VizColor - AE

This visualization shows how average fixation duration changes across problem order for 86 participants in a math problem-solving eye-tracking study, with correct and incorrect responses distinguished by color. A scatter plot displays each problem trial, plotting problem order on the x-axis against average fixation duration on the y-axis, using D3 v7’s scaleLinear, scaleOrdinal, and schemeCategory10 APIs. The data is loaded from a CSV file using d3.csvParse. The chart includes axes and a color legend rendered through custom helper functions, revealing potential trends in attention over time and differences between correct and incorrect answers.

Scatter Plot with mean trend

This scatter plot displays the relationship between problem order and average fixation duration for 86 undergraduate students, with each point colored by whether the response was correct. A red trend line, calculated via linear regression using cumulative sums, shows the overall direction of the data. The visualization uses d3.v7 with SVG rendering, employing `selectAll` joins for marks and axes, `scaleOrdinal` with `schemeCategory10` for coloring, and `extent` for domain scaling. Data originates from a WPI MAPLE Lab eye-tracking study from 2021-2022.

Many plots. Part 2

This gallery example presents a small-multiple scatter plot matrix exploring eye-tracking data from a WPI MAPLE Lab study of 86 students solving math problems. Each scatter plot shows a different participant’s data, plotting problem order on the x-axis against a selected metric (average fixation duration, no-fixation percentage, or response time) on the y-axis, with points colored by correctness. A dropdown menu switches the y-axis variable, while a legend filters points by hover. The visualization displays the raw data with linear trend lines, built using d3.v7’s scaleLinear and scaleOrdinal APIs, and fetches the dataset from a gist.

Dropdown menu AE

This interactive scatterplot lets users explore eye-tracking data from a study of 86 undergraduates solving math problems. A dropdown menu, built with D3.js, dynamically switches the y-axis between average fixation duration, no fixation percentage, and response time. Each point represents a problem, colored by correctness, with a regression line revealing trends over problem order. The visualization highlights associations between response time, fixation patterns, and performance. Data is fetched from a remote CSV and rendered using D3's scaleLinear, scaleOrdinal, and axes utilities.
