ILINet Flu Surveillance Data

ILINet Flu Surveillance Data

This visualization displays national ILI (influenza-like illness) total cases across the years 2015–2019, with each year’s weekly curve plotted as a distinct line. The chart uses a line mark with year encoded as color, revealing seasonal patterns and year-over-year comparisons, such as the peak in 2018 and the extended 2019 season. Built with the vega-lite-api, it aggregates weekly data by summing ILITOTAL per week and year, then renders via Vega-Lite and Vega. The color scale is unordered, making it harder to discern temporal ordering. Data originates from CDC FluView, fetched as CSV via d3.csv.

ILINet Flu Surveillance Data

This visualization displays annual ILI total cases from 2015 to 2019 as overlaid line charts, enabling year-over-year comparison of flu season patterns and peaks. It uses the vega-lite-api and d3.csv to load CDC FluView surveillance data, with vega and vega-lite handling rendering and tooltips. The y-axis shows aggregated ILI totals by week, while color encodes year; the code also includes a Choropleth map interaction option for regional or state-level exploration.

ILINet Flu Surveillance Data

This chart displays the national ILI total flu cases per week from 2015 to 2019, with each year drawn as a separate line to facilitate year-over-year comparison. The ordered color encoding (darker means more recent) makes it easy to distinguish the annual trends. It is built using the vega-lite-api and vega-lite, with data loaded from a CSV file via d3.csv. The aggregator sums ILITOTAL per region and week, and the plot supports tooltips for detailed data inspection.

ILINet Flu Surveillance Data

This visualization displays annual ILI flu case totals across U.S. regions, with lines for each year from 2015 to 2019 plotted against week of year. The chart uses an unordered color scale for the year field, making it harder to compare temporal trends. Built with the vega-lite-api and d3, it aggregates weekly ILITOTAL values by year and region before rendering the line marks. Data originates from CDC FluView Interactive, loaded as CSV via d3.csv, and the visualization supports tooltips on hover.

ILINet Flu Surveillance Data

This line chart visualizes national ILI total influenza cases per week from 2015 through 2019, using color to distinguish each yearly curve. The visualization is built with the vega-lite-api and renders SVGs through Vega and Vega-Lite, with data aggregated by year, region, and week using a transform. The dataset originates from CDC FluView Interactive and is loaded via d3.csv, while the chart encodes week on the x-axis and summed flu cases on the y-axis, with tooltips displaying the year.

ILINet Flu Surveillance Data

This visualization displays annual ILI (influenza-like illness) total cases by week for the US, with color encoding by year to compare flu season patterns across 2015 through 2019. It uses vega-lite-api with d3 to load CSV data from a GitHub Gist, aggregates ILITOTAL by year, region, and week, and renders multi-series line marks over a fitted, full-window SVG canvas. The config file customizes axis and label styling for readability.

ILINet Flu Surveillance Data

This visualization shows ILINet flu surveillance data, plotting weekly ILI totals across multiple years with each year color-coded for comparison. It aggregates ILITOTAL values by year, region, and week, using bar marks to display the data. The code uses the vega-lite-api library to construct the chart, with d3.csv loading the data from a Gist-hosted CSV, and vega-tooltip providing interactive hover details. The visualization applies a custom config for improved label and title readability.

ILINet Flu Surveillance Data

This line chart shows the annual total ILI flu cases in the US by week, with separate curves for each year from 2015 to 2019. The visualization aggregates the data by year, region, and week, then encodes year as an unordered color scale. It uses the vega-lite-api to construct the chart and d3.csv for data loading from the CDC FluView Interactive dataset. The tooltip displays the selected year, and the chart is rendered with a custom configuration for axis styling.
