Stacked area chart

Line Chart with Multiple Lines

The visualization presents unemployment trends across Spanish regions from 2007 to 2014, with a supplementary bar chart detailing 2014 rates by region. It uses D3.js v3 to render SVG elements, including animated line paths that traverse the time series for each region, allowing hover highlighting to emphasize individual trends. The data is loaded from CSV files containing yearly unemployment percentages, with axes and scales built using d3.svg.axis and d3.time.scale.

Bar Chart, Framed

This visualization shows unemployment rates in Spain from 2005 to 2015, breaking down data by autonomous community and province. Two views are available: a bar chart displaying the unemployment rate for 2015 and an area chart depicting the total number of long-term unemployed over time. The bar chart sorts regions by rate and uses interactive hover effects to highlight values. The visualization uses the D3.js library for rendering and animation, with data processed from raw INE microdata via R using the dplyr and tidyr packages.

Line Chart with Multiple Lines

This visualization examines unemployment across Spanish regions with two interactive SVG charts. The first chart displays 2014 unemployment rates as a horizontal bar chart, while the second tracks the evolution of these rates from 2007 to 2014 using a multi-line chart. The line chart uses d3.time.scale and d3.svg.axis to render annual data points, with hover effects that highlight individual paths. Regional CSV data is loaded and sorted via d3.csv, with the darkest bar representing the national total.

Line Chart with Multiple Lines

This visualization displays the evolution of unemployment rates across Spanish regions from 2007 to 2014, with the national average highlighted in a darker gray. Each region appears as a separate line, and hovering over any path highlights it in red. The chart uses D3.js v3 with SVG rendering, utilizing `d3.svg.line`, `d3.time.scale`, and `d3.svg.axis` to map yearly data loaded from a CSV file. Data originates from Spain’s Economically Active Population Survey (INE).

Line Chart with Multiple Lines

This visualization shows the evolution of unemployment rates across Spanish regions from 2007 to 2014, highlighting the national total in a darker stroke and individual regions as hoverable lines. It combines an SVG line chart with a static map image, using d3.csv to load regional data, d3.time.scale and d3.svg.line for the axes and paths, and CSS `:hover` interactions to emphasize selected lines. Data comes from Spain’s Economically Active Population Survey (INE).

Exercise Module 4

This graphic shows the 2014 unemployment rate for Spanish regions as a horizontal bar chart, with regions sorted from highest to lowest and the national average highlighted in a darker shade. It uses a linear scale for the value axis and an ordinal scale with range bands for the categorical region axis. The visualization is built with D3 v3, referencing the CSV data file for unemployment statistics, and uses SVG rendering with custom axes, hover tooltips, and a color scheme that emphasizes the national total.

Exercise Module 3

This visualization displays unemployment rates across Spanish regions in 2014, with a horizontally sorted bar chart ordering regions from highest to lowest rate. The chart uses D3 v3’s `d3.scale.linear` for the x-axis and `d3.scale.ordinal` with `rangeRoundBands` for the y-axis, rendering SVG rectangles. Hovering reveals tooltips via `append("title")`, while the total Spain value appears darker. Data comes from the Spanish Statistical Office (INE), and the axes use `d3.svg.axis`.
