下载 SVGTexas 地图能看出什么
Texas divides into 254 counties — more than any other state, and more than twice the number in the next largest. That count is the whole character of the map. The eastern third is a dense mosaic of small counties laid out when a day's ride defined a county seat, while single counties out west run larger than Connecticut: Brewster alone covers over six thousand square miles. Population runs the other way. Harris, Dallas, Tarrant, Bexar and Travis hold roughly half the state between them in five small shapes near the middle of the picture, and Loving County in the far west has fewer residents than a school bus holds. Any Texas county map is therefore two maps at once — an area map that shouts about the west, and a population map that whispers there — and knowing which one you are drawing is the difference between a chart that informs and one that misleads.
Texas 的三种画法
数值是比率时给区域填色，是计数时用大小不同的标记。把这两者用反，是数据地图最常见的误导方式。
什么时候该画 Texas 地图
Your data is reported by Texas county
DSHS health indicators, Texas Workforce Commission labour figures, TEA school data, Secretary of State election returns and Railroad Commission production tables are all published by county.
You are showing a rate or a share
Uninsured rate, unemployment rate, share of the vote, median household income. Rates are already adjusted for population, which is what shading a region needs.
You want to show the metro-and-rural split
The five big metros against 240-odd rural counties is the fundamental Texas story, and it is a geographic story. A county map makes it something the reader sees rather than something they have to be told.
You need a blank map to print or fill in
Classroom exercises, territory planning, colour-by-hand sessions. The free outline above prints cleanly at any size.
什么时候不该画 Texas 地图
You are mapping totals rather than rates
Shade by a raw count and Harris County wins every time — it holds about one Texan in six inside one of the smaller shapes on the map. Use symbols or bubbles sized by the count instead.
You want county labels on every shape
254 names do not fit. Label the dozen counties your argument rests on, leave the tooltip to carry the rest, and let the reader hover for the ones they care about.
Your unit is a city, a metro or a school district
The Dallas–Fort Worth metroplex spans eleven counties, Houston's spans nine, and Texas school districts cross county lines freely. Squeezing any of these onto counties misplaces the thing you are describing.
Only a few counties have data
Surveys with a state-level sample rarely support 254 estimates. A map with two hundred grey shapes is a worse table — rank the counties you actually have.
如何制作 Texas 地图
从表格到发布上线，一步一步来。
Download the blank map, or start from the template
The free outline above is a plain SVG of all 254 counties — print it, or drop it into a document. To build with data, open the PlotSet Texas (counties) template, which comes with sample data already bound.
Prepare a county column and a value column
One row per county: the county name or its five-digit FIPS code in the first column, your number in the second. FIPS codes for Texas all begin 48.
Upload or connect your data
Import a CSV or Excel file, paste from a spreadsheet, or connect a Google Sheet so the map can be refreshed when the source updates.
Pick the style that fits the measure
Shade the counties for a rate, or switch to symbols or bubbles for a count. Same geography, same data, different encoding — and with Texas the choice matters more than it does anywhere else.
Choose a colour scale on purpose
Sequential for a low-to-high measure, diverging only when a real midpoint exists — the state average, zero change, a 50 per cent line. Four to six steps read more precisely than a smooth gradient across 254 shapes.
Publish, embed or export
Publish for a live interactive map with a tooltip on every county, or export a PNG, SVG or PDF for a report or a deck.

All 254 counties, spelled as the state spells them
Watch the ones that break a join: Bexar, DeWitt, Deaf Smith, Val Verde, La Salle, Jim Hogg and Jim Wells, Palo Pinto, Nacogdoches, Tom Green. Matching on FIPS avoids every one of these.
Texas FIPS codes start at 48
48001 is Anderson, 48507 is Zavala. Store the column as text so the leading digits survive, and note that the county part is odd-numbered rather than sequential.
County names are not city names
Bexar County is San Antonio, Harris is Houston, Tarrant is Fort Worth and Travis is Austin. There is a Dallas County, but Dallas the city spills into Collin, Denton, Rockwall and Kaufman as well.
Where to get Texas county data
The Texas Department of State Health Services, the Texas Workforce Commission, the Texas Education Agency, the Texas Water Development Board and the Secretary of State all publish county tables, as does the Census Bureau's ACS.
Texas 地图上的常见错误
Shading counts instead of rates
It produces a population map every time — the five metro counties glow and the other 249 disappear. Anything that grows simply because more people live there should be a sized symbol, not a shade.
Letting empty west Texas carry the eye
The largest shapes hold the fewest people. A single county with a hundred residents and a striking colour will dominate a map that is otherwise about millions of Texans, so say so in the caption or suppress low-count counties explicitly.
Joining on names without checking spelling
DeWitt, De Witt and Dewitt are three different strings, and a silent mismatch leaves a blank county rather than an error. Join on FIPS where you can.
Using a rainbow colour scale
A sequence of hues has no natural order, so readers cannot tell high from low without checking the legend on every one of 254 counties. Use one hue, light to dark.
