gridmap-layout-california

Positions of tiles for California grid map visualization. Inspired by the Thailand grid map from @kristw

The data files can be found in the dist directory of the installed package. Either one of these files below can be used:

dist/gridmap-layout-california.json
dist/gridmap-layout-california.csv
dist/gridmap-layout-california.js
dist/gridmap-layout-california.min.js

The data in each file is an array of tiles (provinces). Each tile is in this format:

[
   {  
      "x":3, // column index
      "y":3, // row index
      "enName":"Hà Nội",
      "enAbbr":"HN",
      "localName":"Hà Nội",
      "localAbbr":"HN"
   },
   ...
]

Example Usage

One way to use this is to use with D3.js. See a live example on bl.ocks.org. Or you can use the ready-to-use component d3Kit-gridmap.

d3.json('path/to/gridmap-layout-california/dist/gridmap-layout-california.json', function(error, gridmapLayoutCalifornia){
  var options = {
    rectWidth: 25,
    rectHeight: 25
  };

  // Define color scale
  var color = d3.scale.quantize()
    .domain([1, 20])
    .range(['#b2ddf0', '#92bcd8', '#769cbf', '#5d7da7', '#46608f', '#334577', '#232d5f']);

  var svg = d3.select('svg')
    .attr('width', 250)
    .attr('height', 450);

  var sEnter = svg.append('g')
    .selectAll('g')
      .data(gridmapLayoutCalifornia)
    .enter().append('g')
      .attr('transform', function(d){return 'translate('+(d.x*options.rectWidth)+','+(d.y*options.rectHeight)+')';});

  sEnter.append('rect')
    .attr('width', options.rectWidth)
    .attr('height', options.rectHeight)
    .attr('vector-effect', 'non-scaling-stroke')
    .style('opacity', 0.5)
    .style('stroke', '#aaa')
    .style('fill', function(d){return color(d.enName.length);});

  sEnter.append('text')
    .attr('x', options.rectWidth/2)
    .attr('y', options.rectHeight/2 + 2)
    .style('text-anchor', 'middle')
    .text(function(d){return d.localAbbr;});
});

Development

First, generate an output from the force-directed + snap-to-grid approach. The output is available at src/output/step3.csv and can be opened in Excel or Google Sheets to curate manually.

npm run precurate

After editing src/output/step3.csv and save as src/output/step3_curated.csv, run this command to produce the final output and copy files to examples and dist directories.

npm run postcurate
