отличие от карты мира должно быть в том что на странице карта кыргызстана отображался только кыргызстан без других стран

вот что написано на официальном сайте для того чтобы отобразить только одну страну
Style a single country
On this page
Getting started
Create a new style
Step 1: Add a satellite layer
Step 2: Add a mask layer
Step 3: Style the mask layer
Step 4: Hide the mask for one country
Step 5: Add a water layer
Step 6: Add country borders
Step 7: Show more satellite context
Publish your style
Final product
Next steps: Add a data visualization
In this tutorial, you will learn how to style a map with one specific country highlighted apart from other countries. You will use Mapbox Countries, Mapbox Satellite, and Mapbox Streets, three freely available tilesets, with a masking technique to do this.

Masking is a cartographic term that describes hiding features on a map so that the geographic area of interest is the main visual area illustrated, limiting unnecessary visual clutter. In this example, you will be styling The United States and masking all other countries.

Your final map style will look like this:

Screenshot showing a single country styled on a map
Getting started
Before getting started, you will need a few things:

Mapbox account. You will need an account to log in and use the Mapbox Studio style editor. You can create an account at mapbox.com/account.
Create a new style
Log into your Mapbox account and navigate to your Styles page. This is where all your styles are listed.
Click New style to create a new style.
Scroll down and select Blank to create a new style from scratch.
Click Customize Blank. The style editor will automatically open.

What is a style?
A style is a set of rules for how Mapbox will draw the map on a page. It includes references to your data, map images (icons, markers, patterns), fonts, and defines how all your data should be styled on your map. For more about styles, see the Styles section of the Mapbox Studio Manual.

Step 1: Add a satellite layer
First, you will add a new raster layer using satellite imagery from Mapbox.

In Studio, click the Layers tab to open the Layers panel.
Click the plus button (+) to add a new layer. This will open a Layer properties panel.
In the Layer properties panel, click None selected to select a source. Then, search for "Mapbox Satellite" and click raster Mapbox Satellite to select that layer as the layer source. This will create a raster layer called mapbox-satellite.
Close the Layer properties panel.
Your map should look like this:

Step 2: Add a mask layer
Next, you will add a new fill layer using country polygons from Mapbox.

Click the plus button (+) to add a new layer.
In the Layer properties panel, click None selected to select a source. Then, search for "Mapbox Countries" and click the polygon country_boundaries layer from the Mapbox Countries v1 tileset.
Close the Layer properties panel.
Your map will look black because the default styling for a fill layer is black:

How to add a layer using the Mapbox Countries tileset in Mapbox Studio
We will adjust the styling in the next step.

Step 3: Style the mask layer
Next, you will style all country polygons except one, to create the mask effect.

In the Layers panel, click your fill country_boundaries layer.
In the Layer properties panel, set the fill color to white (#ffffff).
All countries are now covered with a white color fill.

Step 4: Hide the mask for one country
Next, you will apply a data condition to style one country differently.

Click the Style with data conditions option, search for "name", and click the name property. This will open a panel where you can set a data condition to define which countries you will apply styling rules to. By default, the Data field will use the is operator.
Click the pencil icon (pencil) and enter the value "United States", then click the plus sign (+) to add this value.
In the Fill color section, drag the opacity slider to the left or set the a value to 0 to make the fill color transparent for features with a name property that is "United States".
Your map will look like this:

A map style with all countries except one covered by a solid color in Mapbox Studio
Step 5: Add a water layer
Next, you will add a new fill layer using water data from Mapbox.

Click the plus button (+) to add a new layer.
In the Layer properties panel, click None selected to select a source. Then, search for "water" and click the polygon water layer from the Mapbox Streets v8 tileset.
Click the Style tab and set the fill color to white (#ffffff).
Your map will look like this, with only one country visible:

How to add a water layer and style it with a solid color in Mapbox Studio
Step 6: Add country borders
Next, you will add a new line layer using national border data from Mapbox.

In the Layers panel, click your fill country_boundaries layer.
Click the duplicate icon (duplicate) to create a copy of this layer. The new layer will be named fill country_boundaries copy .
Select the new layer to open the Layer properties panel, and click the Select data tab.
Click the Type property and change the type from fill to line.
The Mapbox Studio data inspector will display the line data like this:

How to add country borders with a line layer in Mapbox Studio
Click the Style tab, then set the Width property to 0.3 and the Color property to gray: #cccccc.
In the Layers panel, drag your fill country_boundaries copy layer to the top of the layer hierarchy, above all other layers.
Your map will look like this, with visible outlines around the masked countries:

How to move a layer to the top of the layer stack in Mapbox Studio
Step 7: Show more satellite context
Next, you will add some black-and-white satellite imagery to give the masked countries some visual context.

In the Layers panel, click your mapbox-satellite layer.
Click the duplicate icon (duplicate) to create another copy of this layer. The new layer will be named mapbox-satellite copy .
Click the Style tab, then set the Opacity property to 0.3 and the Saturation property to 0.1.
In the Layers panel, drag your fill mapbox-satellite copy layer below your water layer but above your country-boundaries layer.
Your final map style will look like this:

View fullscreen demochevron-right
To begin developing with your new map style, continue to Publish your style.

Publish your style
When you have finished editing your map style, publish your changes by clicking Publish in the upper right of the style editor. When you click the publish button, a window will display the difference between the previous and current version of this style. If you're happy with the changes, click Publish. Your style will now be available to share from a variety of tools and applications.

Final product
You've styled a single country with the help of several freely available data sources. Mapbox Studio provides a wide variety of ways to use your new map style. You can use this map directly on your website or in a web or mobile application. Take a look at the Publish style section of the Mapbox Studio Manual to see all the ways you can use your style!

Next steps: Add a data visualization
You can extend the workflow outlined in this tutorial to add and style additional geometries in Mapbox Studio.

Try adding a choropleth map visualization using the data and instructions from our Make a choropleth map tutorial.
We would love to see how designers use boundaries data with different masking techniques. Share your creations on Twitter with the hashtag #BuiltWithMapbox.

как я понял  карту кыргызстана именно настроить так чтобы отображалась только она , можно в mapbox studio я уже настроил такое 
вот ссылка 
mapbox://styles/justincredible1369/cm2hbatqc016p01r2f8ib1ekn

просто нужно  отобразить эту карту без использования прочих geojson файлов
