This interactive choropleth map visualizes the number of buildings with basements constructed in each Japanese prefecture from 2011 to 2015, based on data from Japan’s e-Stat statistics portal. Users clickable legend labels switch between total counts and counts per basement floor level, each with 1-second animated color transitions. The map uses D3 v3’s `d3.geo.mercator`, `d3.geo.path`, and TopoJSON to render geographies, with zoom and pan via `d3.behavior.zoom`, plus a hover tooltip. A linear color scale encodes values from blue (low) to red (high). Tokyo, Osaka, and Hokkaido show notably higher counts.

2011〜2015のデータに基づく建築着工した地下を有する建築物件数。人口の多い都市部に集中する一方、地方は少ない。例外的に北海道、沖縄が多い。

都道府県別売上の推移

A choropleth map of Japan displays the annual sales figures for each prefecture from 2009 to 2017, with a dropdown menu to select the year. Animated transitions smoothly recolor each prefecture's fill, while proportional circles, centered on each prefecture's capital, scale their radius to represent the sales value. The visualization uses D3.js v3 with a Mercator projection via `d3.geo.path()`, a linear scale for color and radius, and queues external JSON and TSV files to load geographic and sales data.

都道府県別人口の推移

The map visualizes the population change of Japan's 47 prefectures from 1920 to 2012, using a choropleth where color intensity represents population size. A dropdown menu selects the year, and a 2-second transition animates the color changes across all prefectures. Built with D3 v3, it uses the `d3.geo.mercator` projection and `d3.geo.path` to render the TopoJSON map, while population data from the Statistics Bureau is loaded from a TSV file. Capital city locations are added as small circles using the `projection` function.

都道府県別人口の推移

An animated choropleth map shows population change across Japanese prefectures by year. A dropdown menu selects the year; the map transitions its color fill over two seconds to reflect the new population data. Built with D3 v3, the visualization uses `d3.geo.mercator` projection, `d3.geo.path` to render TopoJSON map features, and a linear color scale from white to blue. Population data from the Statistics Bureau is loaded from a TSV file.

都道府県別人口の推移

This interactive map visualizes population changes across Japan’s 47 prefectures from 1920 to 2012. A dropdown menu selects a year, triggering a two-second color transition on each prefecture based on population values, using a linear blue scale. The visualization uses D3 v3 with `d3.geo.mercator` and `d3.geo.path` to render TopoJSON boundaries, while population data is loaded from TSV files via the queue library. Prefecture capitals appear as black circles. Data is sourced from Japan’s Statistics Bureau.

都道府県別人口の推移

This example visualizes Japan’s population changes by prefecture from 1920 to 2012. A choropleth map colors each prefecture according to its population for a selected year, with a dropdown menu to switch years and an animated two-second color transition between selections. Capital cities are marked with circles using projected coordinates. The code uses d3.v3, queue, topojson, and d3-legend, applying d3.geo.mercator and d3.geo.path to render the map from TopoJSON data, while population data comes from the Statistics Bureau of Japan.

都道府県別人口の推移

This visualization shows the population changes of Japan’s 47 prefectures over time, using a choropleth map colored by population value. A user selects a year from a dropdown menu, triggering a smooth two-second color transition that updates prefecture fills. The map is rendered with D3 v3’s `d3.geo.mercator` projection and `d3.geo.path`, with circles marking prefectural capitals. Population data comes from the Statistics Bureau of Japan, and map boundaries use TopoJSON. A color legend built with `d3.legend` clarifies the scale.

都道府県別人口の推移

A choropleth map of Japan shows population change over time for each prefecture, with a drop-down menu selecting the census year. The color scale ranges from white to blue, and white circles mark each prefectural capital. The visualization uses D3 v3 with the Mercator projection via `d3.geo.mercator`, `d3.geo.path` to render the TopoJSON map, and `d3.legend.color` for the legend. Population data comes from government statistics, and transitions animate the color changes over two seconds.
