A choropleth map of the 20 Health NZ districts. Paste your numbers, choose how to band them, export.
Paste two or more columns from a spreadsheet — district names in one, values in another. Tab or comma separated, or drop a CSV onto the map. Names can lead in te reo, drop macrons or use old DHB names; anything it can't place is listed rather than quietly dropped. Then pick the column to map and give it a caption for the legend.
Nothing loaded. The map is coloured by hand.
How values turn into colours. Equal counts puts the same number of
districts in each band. Equal intervals splits the range evenly; rounded snaps the edges to
whole numbers. Bands I type lets you set the edges yourself — type 0, 20, 40, 60, 80, 100.
Typing the bands is what lets several maps share one key, and it keeps empty bands in the legend so the
key reads the same on each.
The palette the bands are drawn from. Shades runs light to dark from your colour. Diverging runs two hues out from a midpoint, for values above and below a baseline. Hues and categorical suit non-numeric data. Click a swatch to pick that colour, or open the picker to change the base.
These ten colours are fixed. Choose another palette type to use the picker.
What gets drawn on the map itself. Text size scales district names and values together, and spreads the leader lines around Auckland and Wellington so they don't collide. Merging shows Capital and Coast with Hutt Valley as one district — Stats NZ publishes both views, and some sources report Wellington only as the merged one.
The key exactly as it will export. With data loaded the band labels come from your bands and can't be edited. With no data, type your own label against each colour.
PNG for slides, SVG to resize or edit later. Legend only gives a standalone key, so three maps sharing the same bands need one legend between them rather than three copies. Transparent drops the white background — the districts still paint. Save bundle writes one zip with the map, the legend and a settings file. Open that zip again later — in a fresh browser, on another machine — and everything comes back exactly as you left it. Everything saved is named after the legend caption and stamped with the date and time. Exports always use the light palette, so a screen in dark mode and the saved image will look different.
A zip holding the map, the legend and the settings that made them. Files are named after the legend caption.
Every district and its value. Click one to select it, Cmd or Ctrl-click to add more, or click a region heading to take that whole region. Selecting then applying a colour is how you shade the map by hand; with data loaded the colours come from the data, so those buttons are off.
