Как конвертировать ASP в MVC

---

У меня есть веб-приложение highchart(круговая диаграмма).Теперь я хочу конвертировать в MVC, как это сделать?
здесь я использовал веб-сервисы и ajax jquery mehod.

Что я уже пробовал:

Веб-сервис

[WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
    [System.Web.Script.Services.ScriptService]
    public class city : System.Web.Services.WebService
    {

        public class cityPopulation
        {
            public string city_name { get; set; }
            public int population { get; set; }
            public string id { get; set; }
        }
        [WebMethod]
        public List<cityPopulation> getCityPopulation(List<string> pData)
        {
            List<cityPopulation> p = new List<cityPopulation>();

            using ( SqlConnection cn = new SqlConnection(ConfigurationManager.ConnectionStrings["dbConnection"].ConnectionString))
            {
                string myQuery = "SELECT id,city_name,population FROM  citypopulation WHERE  year = @year";
                SqlCommand cmd = new SqlCommand();
                cmd.CommandText = myQuery;
                cmd.CommandType = CommandType.Text;
                cmd.Parameters.AddWithValue("@year", pData[0]);
                cmd.Connection = cn;
                cn.Open();
                SqlDataReader dr = cmd.ExecuteReader();
                if (dr.HasRows)
                {
                    while (dr.Read())
                    {
                        cityPopulation cpData = new cityPopulation();
                        cpData.city_name = dr["city_name"].ToString();
                        cpData.population = Convert.ToInt32(dr["population"].ToString());
                        p.Add(cpData);
                    }
                }
            }
            return p;
        }

    }

}

Jquery на странице aspx
