    <p><strong>GIS to Topojson:</strong></p> <p>I'm using <a href="http://diva-gis.org/" rel="nofollow">DIVA-gis.org</a> for my data source. I've downloaded the data for Armenias administrative areas. This dowload produces a .shp file. I've tried to pass it directly to topoJSON and I get a json file as follows<br></p> <pre><code>Object { type: "Topology", objects: Object, arcs: Array[1], transform: Object } </code></pre> <p><strong>Topojson to SVG:</strong></p> <p>I'm pointing d3 to objects.armenia which contains my geometries property. The problem is that that geometries property contains an array of arcs which is 0. Now within my topoJSON of armenia I do see an arcs property array that contains quite a big array of values... I've tried pointing my d3 code to that element but I still get nothing.<br> Aside from that I've also used QGIS to convert my .shp file into geoJSON and them use topoJSON to go from geoJSON from topoJSON... but still nothing. My d3 code is as follows<br></p> <pre class="lang-js prettyprint-override"><code>var width = 960, height = 500; var projection = d3.geo.mercator() .scale(1000) .translate([width / 2, height / 2]); var path = d3.geo.path() .projection(projection); var mapContainer = d3.select("#armenia").append("svg") .attr("width", width) .attr("height", height); d3.json("/ARM_adm/output.json", function(error, country) { console.log("country",country) mapContainer.insert("path", ".graticule") .datum(topojson.feature(country, country.armenia)) .attr("class", "land") .attr("d", path); }); </code></pre> <p>I simply get an empty path... any help would be much apreciated.</p>

    2. COI'am confused, is your topojson JUST these 6 lines of code ? (about 200 characters). May be good if you share your ogr / topojson commands as well.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
