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.

AI-generated description

A visualization constructed using the vega-lite-api.

This graph shows the national ILI total cases annually. The curves from 2015 to 2019 to the present date are displayed. This plot achieves the visualization of the annual ILI total patterns in general, and also provide a direct comparison year-over-year. We can tell 2018 is the year with highest Flu cases in mid February time, while 2019 has a more stretched Flu season comparing to other years.

When interactions are introduced for the visualization together with Choropleths Map, we can select the individual yearly curve and present the map for that given year. We can also select a region or state and present a different portion of the dataset here to see more localized patterns.

ILINet Flu Surveillance Data

This visualization displays national ILI total cases per week for each year from 2015 to 2019, using multi-series line marks to compare seasonal flu patterns year-over-year. The chart aggregates ILITOTAL values by year, region, and week, with color and size encoding the year. It is built with vega-lite-api, vega-lite, and d3, pulling data from a CSV fetched via d3.csv. The data originates from CDC FluView Interactive, and the visualization is configured with custom axis and label styling.

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 visualization uses a multi-line chart to show annual ILI total flu cases in the US from 2015 to 2019, enabling year-over-year comparison—revealing the 2018 peak and the extended 2019 season. Ordered color encoding on the year field makes newer years darker for readability. Built with Vega-Lite API via `vl.markLine`, it aggregates data by year, region, and week, using `vl.sum('ILITOTAL')`. The data originates from CDC FluView, loaded as CSV through `d3.csv`.

ILINet Flu Surveillance Data

This visualization displays national ILI total flu cases from 2015 to 2019 as overlaid annual curves, highlighting yearly patterns and enabling direct comparisons. The chart uses an unordered color encoding for the ordered year field, which impairs readability because viewers cannot infer temporal order from color alone. Built with vega-lite-api and d3.csv, the code loads data from a Gist containing CDC FluView Interactive data, with vega-tooltip providing interactivity and a custom config for axis styling.

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 line chart displays annual national ILI flu cases across weeks, with each year’s curve overlaid for direct comparison, revealing 2018’s peak in mid-February and 2019’s extended flu season. The visualization aggregates total cases by year, region, and week using an ordered categorical color scale for years, though the encoding is unordered despite the temporal field. Built with vega-lite-api, vega-lite, and d3.csv, it renders via SVG from CDC FluView Interactive data, with axes and styling configured for readability.

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.
