This scatter plot visualizes the relationship between age and maximum heart rate for individuals in a heart failure prediction dataset from Kaggle. Each circle represents a person, positioned by age on the x-axis and MaxHR on the y-axis, with most data points clustered between ages 40 and 70. The visualization uses d3.scaleLinear for axes and d3.scaleOrdinal for categorical coloring, with semi-transparent circles (opacity 0.6) revealing overplotting density in darker overlapping regions. Outliers with unusually high or low heart rates for their age appear scattered throughout the plot.

AI-generated description

A scatter plot with D3 showing the heart-failure-prediction

The plot shows a wide distribution of maximum heart rates across different ages.

Axes:

  • The x-axis represents 'Age' in years.
  • The y-axis represents 'MaxHR' (Maximum Heart Rate) in beats per minute (bpm).

Data Points (Circles):

  • Each circle on the plot represents an individual from the dataset.
  • The position of a circle is determined by the individual's age (along the x-axis) and their maximum heart rate (along the y-axis).

Obesrvations

  • By looking at the scatter plot, you can observe how maximum heart rate varies with age among the individuals in the dataset.
  • The majority of the data points seem to be clustered between the ages of about 40 to 70 years.
  • There are some potential outliers, such as individuals with very high or very low maximum heart rates for their age group.
  • The varying opacity of the circles indicates overplotting; where data points overlap, the circles appear darker. This suggests that in the densest areas, many individuals have similar age and maximum heart rate values.

Heart Disease Scatter Plot

This scatter plot shows the relationship between patient age and maximum heart rate achieved using data from the Heart Disease UCI Kaggle dataset. Each blue circle represents an individual patient, with age plotted along the x-axis and maximum heart rate along the y-axis. The visualization loads CSV data via `d3.csv`, parses numeric fields, and renders circles as SVG elements with `d3.scaleLinear` for both axes. Axis labels are added manually using SVG text elements, while axes themselves are generated through `d3.axisLeft` and `d3.axisBottom`.

Heart Disease Scatter Plot

A scatter plot maps patient age against maximum heart rate achieved, with each circle colored by sex (red for female, blue for male). The visualization uses D3 v6 to load CSV data from a GitHub Gist based on the Heart Disease UCI Kaggle dataset. SVG circles are positioned with d3.scaleLinear scales and axes are rendered via d3.axisLeft and d3.axisBottom. The plot reveals heart rate patterns across age groups and sex differences in the dataset.

heart-failure-prediction

This visualization explores how clinical attributes contribute to heart failure risk using the Kaggle heart-failure-prediction dataset. Two interactive charts examine gender differences and the impact of factors like age, chest pain type, and maximum heart rate on disease outcomes. The code loads data from a CSV file, converts numeric fields, and renders visualizations using JavaScript within a VizHub iframe. The example demonstrates data parsing and chart construction without specifying particular D3 API calls in the visible code.

Draft Heart attack dataset

This scatterplot uses a heart disease dataset from Kaggle to explore the relationship between maximum heart rate achieved and resting electrocardiographic results, with age on the vertical axis. Each circle represents a patient, colored by gender. The visualization is built with React and D3 v5, using `scaleLinear`, `scaleOrdinal`, `extent`, and `format` from D3, with SVG rendering via custom `AxisBottom`, `AxisLeft`, and `Marks` components. Axes are drawn with D3’s tick generation, and hovering shows tooltips via SVG `<title>` elements.

Iterated Work: Heart Disease Scatter Plot

This scatter plot shows the relationship between patient age and maximum heart rate from the Heart Disease UCI dataset, with points colored by gender (crimson for female, dark blue for male). The visualization uses D3 v5 with SVG rendering, employing `d3.axisBottom` and `d3.axisLeft` for gridlined axes, `d3.scaleOrdinal` for the categorical color mapping, and the `d3-legend` library for the color legend. The data is loaded via `d3.csv` from a GitHub gist, with the sex attribute transformed from numeric codes to strings for labeling.

Reusable Scatter Plot of Heart Disease Dataset

This interactive scatter plot visualizes the Heart Disease UCI dataset from Kaggle, mapping patient age on the x-axis and maximum heart rate achieved on the y-axis, with points colored by sex (red for female, blue for male). Built with D3.js, the visualization uses a reusable scatter plot module that supports dynamic axis updates, animating through different x-axis attributes (age, thalach, restecg) every two seconds using `setInterval` and `transition().duration(1000)`. The SVG renders axes via `axisLeft` and `axisBottom`, with data loaded asynchronously via `csv`.

03_02 Draft for Heart Attack possibility

This scatter plot explores factors linked to heart attack risk, plotting age against maximum heart rate achieved. Each point’s color indicates the patient’s gender, with opacity revealing overlapping points. The visualization uses the Vega-Lite API with D3.js to render interactive marks, pulling data from a UCI Heart Disease dataset. Tooltips display precise values for age and heart rate, aiding in pattern identification across demographic groups.

Fork of Scatter Plot with Menus - Heart Disease Dataset

This scatter plot visualizes heart disease patient data from the UCI dataset, mapping age against maximum heart rate achieved. Users can dynamically change both axes via dropdown menus, selecting from quantitative variables like resting blood pressure or categorical options like patient sex. Built with D3 v6, the visualization uses `scaleLinear` and `scalePoint` for axis scaling, with smooth transitions animating circle positions and radii. The plot renders as SVG, with circles colored by patient sex (red for female, blue for male) and axis updates triggered through custom menu components dispatching change events.
