Anxiety - Avg House price statics in London
This interactive visualization examines the relationship between anxiety Net Promoter Scores and average house prices across London boroughs. A choropleth map displays geospatial data from a TopoJSON file, with borough colors representing house price statistics for selected years. Users can hover over areas to view detailed NPS and pricing information, while a linked line chart generated with vega-lite-api tracks trends over time. The visualization uses d3 for map rendering, topojson for geographic data processing, and SVG output for crisp graphics.
AI-generated descriptionThis variant of the original work by Yu Zhang demonstrates use of an ordered color encoding for an ordered field (year), which makes it easier to read the chart, because you can say "darker is more recent".
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 interations 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.
